I have a 100g growout tank and introduced a trimac pair several months ago. Both were about 0.75 in big, but have grown tremendously over the past 9 months. The male is now about 10 in. I have an umbee in the tank that is a bit older.. about 2 years and hit a growth spurt and is now 11 in. The umbee is very aggressive and will harass my trimac pair. I plan to move these fish into a bigger tank, but can they co-exist. The umbee and male trimac are about the same size. The umbee is 11 in but the trimac actually is bulkier at 10 in. I'm thinking it's only a matter of time when the trimac gets older he will be able to hold his own because I've heard trimacs are also aggressive. Tell me your opinions. Maybe I should keep them separated, but I've always wanted to keep a community in a 200+ gallon tank if possible. Has anyone kept mature umbees and trimacs in the same tank?
