One of the five tanks I have, it's a 2.5 gallon NatGeo Betta tank that I'm using to breed ramshorn snails in anticipation for another tank I'm going to purchase to use as a pea puffer tank. Because the pea puffers eat snails. Ramshorn are just the prettiest of the pest snails.
Three of the other tanks I have are Fluval spec 2.5 gallons for each of my betta.
The last tank is a 9 Gallon community tank that I plan on upgrading to a 20 Gallon. The 9 would be my puffer tank.
