Im thinking of getting him a 72"x36"x25" (lxwxh) tank in about a year or so, once he hits round 15"
And the only fish in my 180 he wouldn't kill is my Oscar. That leaves my Salvini, Festae, GT, Carpinte, and Loisellei. I tried putting my Loisellei in with him, that didn't work, My old Carpinte would have raped him because he was much bigger, and the Jag he would battle all the time, but due to the extreme size difference, he became the less dominant fish. Then my Pacu sacrifice got ick in my friends tank, so he flushed it. Figured it would be cheaper to buy a new one then get the chemicals to treat the ick. I could try and put him in the 180, but it wouldn't be as entertaining a tank with only two cichlids plus my cats and plecs.
