Betta In A 20 Gallon Hexagon?

[onidrase]

I'm in the predicament of finding out what to do with my 20 gallon after it's done being my quarantine tank and I get a 10 gallon for hospital purposes

I always thought bettas were really boring fish. But that's because the LFS told me to keep them in those little quarter gallon containers as they'll be too "insecure" or something if they have too much space.

At that time, I was only like 9, so I didn't question the authority figures. And I got a quarter gallon tank and a betta. Which ended up dying cause the LFS also told me they didn't need filtration or heating. Poor things are just set up for mass murder by the looks of things

Anyways. I'm ready and willing to give them another shot, only this time with the 20 gallon hexagon. I'm assuming this will be more than enough space for the guys. But that's my assumption. It's got plenty of water, but the footprint is only 16 inches long and wide.

I'd like to have some other fish in there, though, honestly. Some small bottom feeders like oto's and pygmy cories, and maybe some glowlight tetras or anything else for that matter.

I'd love some harlequin rasboras, but new debate suggests a 4 foot long tank for them, I guess. And this tank is only tall with like 16 inches of length and width.

What I have in mind is:
1 Male Betta
6 Glowlight Tetras
5 Otos
6 Pygmy Cories (if it has enough space on the bottom. Still gotta research that.)

Would this sort of stocking be alright? What other types of fish would you suggest that can be homed in a hexagon with a betta?

Thanks much.

If it has enough space on the bottom, the cories should be fine, though a 20 gallon long would be best. The glowlights should be alright, though ottos aren't the hardiest of fish and do best with blanched vegetables (such as zucchini) if I remember rightly. I'm not 100% sure on how the otos will get along, but I'm sure someone else will be able to guide you better with this. Hopefully the betta will be a relatively peaceful one and get along with the other fish fine - sometimes they can be rather agressive and kill tankmates.

Oto's do enjoy shoaling. They're less solitary than plecos and the like. I would get a 20 gallon long if I was getting a new tank, but I'm just stocking first tank which I got from my aunt rather than buying something new.

I recently put oto's in with my male betas to handle an algae build-up and they seem to be doing just fine. They go around and eat the algae and the betas dont seem to notice them or really even care. Seems like a good match to me.
