After going thru 3 bettas last week, these guys have been doing great! The red and blue one (Durham) is very active. I have a 5 gallon tank that I am going to divide so Durham can have his own tank. The one he is in right now is split with (Oliver) and he is always flaring at him. And then Xavier is in the 5 gallon by himself but that will soon be split. Durham is a red and blue VT, Oliver is a pink and purple CT and Xavier is a purple and white VT.
