In planning my 29 gallon, I've allocated 2 gallons per snail (3 snails); one gallon each for albino cory cats (6 cats); the rest is for a female betta sorority: 12 gallons, which should probably be 6 bettas (and A LOT of plants to hide in!)
Does my math work out?
(These huge snails are heros at keeping the bottom of the tank clean. I've cyled the tank; added plants, snails, then the corys. I'm going to add a few more plants (some floating), and then plan on getting the bettas Wed.)
4 bettas: Butch, 3-year-old violet male PK EE & 3 girls in a 30 gal sorority. I do not name the girls anymore! 1/2 of them die within a month.
30 gal: 9 Oto cats, 4 Ocellifer cats. Inverts: Cherry shrimp & 2 assasin snails.
10 gal.: Butch, his 5 oto cats, 3 assasin snails, and a few snails the assassins haven't caught.
