Ok thanks everyone! The temperature is fine i have a heater made for bettas, and the thermometer says 78.
I will give him mosquitoe pupae (he prefers them, easier to see and catch) but only wen i can get them from my back yard. I have special buckets I get them from.
other things to do efore then? I mite put him in a bigger tank if i dont put another community set-up in there.
thanks everyone for ur answers!
