since i'm most likely goin to rehome the oscar, if the rtm isn't a good fit, what would've to replace the oscar? I need some color in the tank
Things change fast when cichlids hit a certain size. No way to tell who will snap if any.
I've nerver had rtm so wont comment as fact but read pleanty of threads saying they were aggressive.
Im the wrong person to ask this quesrion lol.
If it were me i would think what i want the center peice of my tank to be then build around it. Rtm will eventually provide you with all the color you need. If its cichlids then i say rehome the bichir if its bichirs then think about a set up that better suits them.
Im not saying you even have to rehome anyone wait and see if it aggression becomes a problem... i think it will but thats just my opinion and could be wrong.
Also watch out for the clown loaches if they are small enough to fit in the endlis mouth and it eats its it chances are both are gonna die. Iwould be extra cautious of this since your endli isnt eating enough as is anday get desperate enough to try. Was a thread in the polypterus section the other day and a 13ish inch endli died while trying to eat a CL.
Also see what others say about the subject im basing my comments on my experience others may have a different point of view.
Ive successfully kept pearsei (minus the feeding drama), aequidens metae, and heterospilus with bichirs... vieja argentea and zonatus were failures not surprisingly
