Hi. I need some advice. I got my Betta a month ago and was feeding him dry blood worms. I understand that these is not good because it has a high fat content and should only be as a treat when it comes to Bettas. So this evening I purchased some food by Tetra called BettaMin (small yellow container). My Betta doesn't seem to eat it at all. He takes it in and spits it out. So I tried some mashed down pease and he eats tgis all up. Any idea how to get him to eat the flakes?
