hey, i just bought a beautiful white crowntail from petsmart. this is my second betta and i've had my other for about three months now and he's doing just fine. the problem is my new white one won't eat anything at all and spends a lot of time sitting on the bottom. he seems to look pretty normal and healthy and has started to swim around a little more (he's in a half gallon tank right now unfortunately, im going to buy him a two gallon like my other later this week) but he still refuses to eat. should i just wait a little while for him to get more acclimated to the tank or do yall think this could be more serious?
