well i have my betta in a 2.5 gallon unfiltered and unheated, he gets a 100% water change every other day, and the lamp next to his tank keeps him warm
i just bought a small heater for the tank, the temp is slowly rising. So i think i'm going to get a beta fish. Any suggestions on which kind? i know there are a few varieties out there.
Veiltail is the most common type of betta, nearly all pet shop sell these, others are Crownttail, Halfmoon, Deltatail(i think), Plakat. These are the more rare ones but Crowntail can also be found in most pet shops.
