I spotted my convict trying to eat my betta fry, he did however get 1 before I could save both. Right now my current 1 is in a breeding net waiting for his new tank Im buying for him. I am going to try to get a 3 gallon but will he be alright in a 2 gallon? Im asking because I see many of you hold bettas in a 2.5 gallon and no less.
