I forgot to share this picture I took of my tanks after I decorated for Halloween, and I figured I’d share a few more pictures, since I haven’t in awhile.
I’ve since moved the pumpkin to my mouse tank, but the window clings will remain until probably Thanksgiving, if I’m being honest.
A rare photo of Salsa the badis and Mothra the dwarf anchor cat hanging out while they enjoy some blood worms (I don’t think I’ve posted Mothra here, before).
 Salsa and Queso checking out some amano shrimp I added to the tank, which didn’t last very long, and I’m not sure why, except that I spotted Hannibal snacking on a molt or two. I moved the surviving two of four to my moss tank (which I tested, by the way, and the parameters are actually perfect, though I wouldn’t add anything else), and now I can’t find them in there, but I’m still seeing molts.
Two additional dwarf anchor cats that I only just took out of quarantine and added to the tank. I named these two Rodan (the lighter one) and Godzilla (the giant one, at a whole 1.5″).
Rainier being a creep while I was attempting to take a picture of the new cats.
Hannibal resting in the sand after taking out a snail I added for him in less than 24 hours.
Look at him. Side note: he’s actually grown a bit, which I only just noticed. I think he’s eventually going to be the biggest one in the tank.
DISCLAIMER: I’m absolutely done stocking my 10 gallon, at this point, and I only added more jerdoni because the badis kept to themselves, the jerdoni don’t even seem to notice the badis are there, no one is getting out-competed for food, and I knew that Mothra would benefit from companionship (though I didn’t know just how much). I know a lot of people who think a 10 gallon is too small for more than one species, and I absolutely agree, with the exception of these two species (people aren’t kidding when they say the catfish really, really don’t move much, except when feeding, and the badis spend most of the day slowly stalking microfauna and each other around the tank), so PLEASE don’t go throwing a bunch of nano fish into a 10 gallon, thinking they’ll work. This is an extremely fine balance of two very unique species that you’re likely not going to be able to emulate with anything other than these exact two species in these exact numbers (I really don’t recommend more than a pair of badis in a 10 gallon, by the way, whether or not you add jerdoni).

Fish Room Wish List?
Just a species list for now, but this could turn into real tank planning talk.
In no particular order:
Hyalobagrus flavus, "Shadow Catfish"
Erethistes/Hara jerdoni, "Anchor Catfish"
Pethia gelius, "Dwarf Golden Barb"
Parosphromenus sp., "Licorice Gourami" (Species will be most dependent on ethical availability.)
Betta sp., Wild-type Betta (B. foerschi? B. raja? What happened to my list of best Betta spp....)
Trichopodus leerii, "Pearl Gourami" (high on the wish list but unlikely any time soon due to size and social requirements)
Kryptopterus vitreolus, "Glass Catfish" (see above, but likely to prioritize these more because wow I love them so much)
[undescribed Petruichthys sp.], “Rosy Loach” (hmm...perhaps I ask Dr. Coolguy why no one’s described these yet)
Ambastaia sidthimunki, “Dwarf Chain Loach” (see notes on T. leerii)
Microglanis sp., “South American Bumblebee Catfish” (Been eyeing M. poecilus and M. cottoides but apparently this genus is a mess so who knows if the fish I like actually belong to these names.)
Microsynodontis sp., “African Bumblebee Catfish” (eyeing M. emarginatus and M. hirsutus)
Maybes....
Badis sp. or Dario sp., ex. "Scarlet Badis" 
Sphaerichthys osphromenoides, "Chocolate Gourami" 
Boraras sp., Micro “Rasboras” (Not sure which I would want, might be influenced by how many blackwater tanks i end up with vs how many I want to set up - if I go clearwater, it would likely be B. urophthalmoides.)
Bunocephalus coracoideus, “Banjo Catfish” (Really want one or some, but they aren’t small so I don’t know how likely I am to get them soon.)
Tatia orca, “Ninja Woodcat”
Corydoras hastatus, “Tail Spot Pygmy Cory”
Unlikely to be available, but would buy in a heartbeat:
Any and all Nanobagrus spp.
Pseudomystus funebris
Pseudomystus leiacanthus
Tachysurus spilotus
I absolutely will have missed some non-catfish from this list so I’ll have to come back to it and edit as I remember to. I am certain there are glaringly obvious wonderful fish species that I would very much love to keep missing from this list that I’ll be aghast at having forgotten whenever they eventually do come to me.

Would glass catfish be okay with a betta pr not work the risk? Thanks!
You know, of all the choices there are, glass catfish are definitely among the better ones since I don’t think they’d stress your Betta out too much. The only thing I fear, however, is that those long feelers would prove irresistible to a bitey Betta. If you want to keep your Betta with other fish, my favorite choices are kuhli loaches and maybe Hara jerdoni if you can find them. They just wriggle around on the bottom of the tank so the two species won’t come across each other much.

Beyond the Betta
I want to preface this: I loved bettas, at one point when I was about 15 I had well over a dozen bettas. Nothing could stop me, especially when Minibow 5’s were constantly on sale. I still like bettas, I think they have a ton of personality and they’re really fun, engaging fish that are incredibly accessible and are pretty cheap to set up. The unfortunate thing is that bettas are sick, they’re overpriced genetic disasters which can be a grab bag of problems. Bettas ten years ago aren’t the same bettas we have now, we have so many different varieties in such a short span of time, all due to inbreeding offspring to parent or offspring to offspring in order to preserve, expand upon, or replicate a desirable trait that sprung up from the genetic mish mash that bettas are. I still assert that non-dragon scale plakats, normal veils and crown tails are some of the healthier bettas you can get.
Now, I am NOT saying that you’re a bad person for having a betta of whatever variety, healthy or not. I am not telling you to get rid of your betta or to never ever get a betta again. You can have your bettas, you can get future bettas. This isn’t an article that’s telling you to get rid of your bettas. I know that everyone leaps to that conclusion any time I or others make posts critical of modern bettas and their ‘designer’ varieties.
But the thing is, you don’t always need to go back to bettas. You can expand your horizons and choose healthier fish in tanks that people normally just leave for bettas. All of these fish have their own charms and quirks, and while some might not have the same pizazz that you expect from bettas, they’re still worthy of appreciation.
The tanks I’m using go from 10 gallons through to 20 longs, which are the most common sized tanks I see people here in the fishblr community keep their bettas in. These are just the minimums, you can always keep your fish or inverts in larger tanks! The tank sizes are simply launching pads, or for you to repurpose an existing tank you already have but have no inhabitants for yet. Keep in mind that 5 gallon tanks are teeny, they’re only 16x8x10, which is too small for me to comfortably suggest to house stock in. Price wise, you’re getting more bang for your buck if you purchase a 10 or a 20 long, especially if you take advantage of the dollar per gallon sales that Petco, Petsmart and Pet Supplies Plus have throughout the year. They’re almost never ending, right after one store has the event going, another pops up. So you have the opportunity throughout many months of the year to get a decently sized tank for relatively little money, and these smaller tanks are light enough that basic furniture in your bedroom can support them, so you don’t need to worry about finding pricey stands.
NOTE: I’ll be mostly linking to Seriously Fish, and a few others, but don’t just rely on those links for all your care needs. Explore!
NOTE VOL 2: I have updated this list and removed the category for 5 gallon tanks, as I no longer feel comfortable making suggestions for tanks this size. 
Let’s move on to the lists!
TEN GALLONS:
Hara jerdoni: anchor cat, Asian stone cat. These little cats can be shy and are most active at night. The fun thing about these guys is that they are so unique, but are not impossible to find, and you can make your own teeny biotope-ish tank. Dwarf shrimp: everyone knows these guys, neocardina or cardina, they’re fun, yet sometimes pricey, little inverts. Thai micro crabs: another little invert, these guys are really unique and charming but they can be shy and like to hide during the day.
Pea puffer: probably the closest in terms of rambunctiousness and personality to bettas, these little puffers are curious, clever and quickly become little delights in your home. If you can handle live feeding of white worms or black worms, I highly suggest these little puffers.
Scarlet badis: Well known but frequently overlooked, scarlet badis are beautiful little gems that would make wonderful little specimens in any tank.
Heterandria formosa: the least killifish, these shy little guys aren’t actually killis but are related to guppies and endlers! They’re very hardy and very easy to breed and make excellent beginner livebearers if you don’t wanna go the more common endler or guppy route if you’re interested in starting up a little breeding project. Note: be mindful of your stocking with livebearers, your tank can be overcrowded quickly.
Neoheterandria elegans: the tiger teddy, another micro livebearer, these are a less forgiving than the least killi, but no less rewarding to keep. If you maintain clean and perfect water conditions then you’ll have no problems keeping these cuties. Note: be mindful of your stocking with livebearers, your tank can be overcrowded quickly.
Endlers: now we’re getting a teensy bit bigger, endlers are gaining popularity in recent years and it’s easy to see why, they’re as hardy and easy to breed as guppies but half the size! And they come in an array of stunning and unique colors and patterns. Note: be mindful of your stocking with livebearers, your tank can be overcrowded quickly.
Pygmy sunfish: sweet, undemanding little natives, these fish are a great way to introduce yourself to fish native in the US.
Sculpins: another little native, they’re sometimes referred to as “ugly” but I find their permanent scowls to be endearing. They’re easy to house and don’t require much else from sand and rocks in terms of decor, so you don’t need to worry about plants.
Taiwanese micro goby: A unique little guy, they’re simple to keep if you neutral pH and soft to mid water, they can be kept similarly to other hillstream gobies such as Rhinogobius nagoye, and they’re non-aggressive so you can house a trio in your tank, more if you get a bigger tank. A great fish if you're looking to create a hillstream tank.
TWENTY GALLONS (long):
Chili rasbora and other boraras: my absolute favorite nano fish, they are absolutely tiny, truly miniaturized fish! They display a great amount of curiosity that you wouldn’t expect from such a small fish, and are honestly one of the best fish I’ve ever kept. They’re great if you’re looking to start up a small biotope tank and want an excuse to add botanicals and do something really fancy.
Pygmy cory, salt and pepper cory, and tail spot cory: the three smallest corydoras in the genus, and the only ones suitable for tanks under 30 gallons! They’re charming and absolutely adorable and probably my three favorite corydoras out there.
Ember tetra: hardy, cute and beautifully colored, these tiny tetras would be perfect in any 20 long, perhaps paired with one of the above species of cory to create a ‘micro community’.
Gold tetra: lesser known but not a small presence, gold tetras actually get their colorations from a symbiotic relationship with a parasite that results in their gold coloring, but with the absence of this parasite they’ll be a stunning silver. They’d be perfect for a small scaled, blackwater tank filled with driftwood and botanicals.
Ruby tetra: very tiny and very pretty, the ruby tetra is a great little fish that would work well in a planted, driftwood filled setup.
Akysis vespa: a very cute, very tiny little cat that prefers cool, soft waters and would be great for a mini hillstream setup! No plants to worry about, just glorious rocks and sand.
Dwarf pencilfish: another cute South American that would pair well with one of the above mentioned corydoras in a mini biotope.
Rainbow darter: personable little natives that will love to hop over to you when they see you approach the tank, these darters are hardy and tolerate the harder waters that the midwest and great plains areas are notorious for having.
Sparkling gourami: a tiny relative of the betta, the sparkling gourami is a shy little jewel of a fish that will thrive in a well planted tank.
Licorice gourami: another small anabantoid, like the sparkling it’ll appreciate a well planted tank and you’ll appreciate its gorgeous colors.
Forktail rainbowfish: while many pseudomugil would be appropriate for this size tank, my favorite is the fork tail. They’re busy little guys and the males put on very amusing little display dances when sparring.
Multiple wild bettas: there are NUMEROUS species of wild betta that can be kept in a 20 gallon tank, if you’re interested I’d suggest sending elemental-kiss an ask.
Many killifish: these would suitably need their own post to cover the vast array of killis there are on the market, and the difference between annual and non-annual, but there are multiple killis that would do just fine in a 20 and spawn well.
Shell dweller cichlids, aka shellies: charming little fellas that exhibit some incredibly amusing behaviors and are easy to breed! Great beginner cichlids.
CPO crayfish: these little dwarves have just as much personality as their full-sized cousins!
There are countless more fish that I may have forgotten or simply left out, but all of these fish would do well in the smaller tanks that we typically keep bettas in. It’s good to move out of your comfort zone and learn how to set up new tanks for different fish with different needs, as setting up the tank and exploring the natural habitats of each fish in your own home is one of the major high points of the hobby. So go ahead, start something new and exciting!

The new stone cats are so neat! I've noticed that they like to perch on things like the corydoras do! Beautiful little fish.

hey! at work one of my kids' parents got a 20g tank for one of the kids' birthdays. they want to get at least three fish [one for each kid] and the oldest pretty adamantly wants a tiger barb- i wasnt super keen on a solidary tiger barb but when i talked to them she was p firm about it. mom said she'd get back to me before they bought the fish, though, so I'm wondering what you'd suggest for at least 3 fish in a 20g with almost definitely a tiger barb
Unfortunately, that’s not gonna work. Tiger barbs are aggressive schoolers. If they don’t have members of their own species in adequate numbers, they will resort to bullying other fish. And if they’re in a school that’s too low in numbers, they will bully each other. And therefore they need big schools in big tanks, so a 20g just isn’t going to work out.
It sounds like they’re beginners, so I doubt they’d be interested in wild bettas or Hara jerdoni. One thing they could do is each kid picks a group. One kid picks the schooling fish, another picks the bottom dweller, last picks a snail. So for example, the oldest chooses neon tetras and the middle child picks pygmy corys and the youngest picks a red racer nerite snail. 
If all else fails, they should stick to one schooling fish and then each pick out a snail or something. A school of neon tetras on black sand would look lovely and the kids would get excited by the colors :)
