I think the trimac will be the king of that tank. The festae will get out grown fast, the carpintis is all bark and no bite compared to the trimac & the jag will be lucky to get food if hes always hiding like all of mine did.
IME, the Trimac grows faster than any of the others you have and just spends its time looking for a fight, which none of the others you have (again, IME) do. Trimacs also have sharp long teeth, similar to a jags.
Ive never had a jag that could hold its own against anything in my tank, BUT...I havent kept one past 8 inches, so, according to everyone else, it might change. I personally dont think so though.
