It's a 29 gallon :/ so far they are doing great, it's seems like the Acie isn't getting along with the peacock, the peacock seems to be the dominate in the tank, the Acie was removed from the tank because he seemed to be beaten. The peacock so far has gotten along with the Yellow and the Auratus. Surprisingly... The Auratus doesn't seem interested in harming any of the other fish. The Peacock is the one that can't get along with the Acie, and the Yellow is fine with everyone so far, so far it's just the 3 fish in the tank, the Yellow, Auratus, and Peacock. The peacock is the most dominate. Is he a male? Thanks for helping too
The tides would likely turn in the future, as they mature. The Acei will outgrow the Peacocks and could potentially start becoming aggressive with them. It will at least not put up with being bullied by the Peacock. More likely, though, is that that Auratus will terrorize both of the others when it comes of age.
Yellow Labs are probably the most peaceful of the Mbunas, and IMO would probably coexist with the Peacock and/or the Acei just fine. Yellow Labs can get 5" though, so that still seems tight for a 29 gallon.
I'm not entirely convinced that the Peacocks could not coexist with the Aceis, but I defer to folks who have had experiences trying to get both to coexist. At least Garfy recommends not mixing Mbuna (Lab and Acei, in your case) with Peacocks.
There are varying opinions on how much tank Aceis need. Some say 4' horizontal, some say 6' horizontal. As well, be advised that, if there are multiple Aceis, some say Aceis need to have multiple females/male, or the males could harass the females to stress them to death. I was once advised a 6:1 ratio was recommended.
So I guess here are my recommended options:
A. Trade them all back in and get Cichlids that can be kept in a smaller tank (search the posts here, you will find some recommendations).
B. Get a bigger tank (4' 55 gallon at least), rehome the lab, the acei, and the peacock (you could still be taking somewhat of a risk, see above), and trade back in or get a third tank for the Auratus. Then you can still get the appropriate Cichlids, etc for your 29. You could add more fish to all of your tanks with this option.
C. Keep them all in this tank and roll the dice. Be warned: aggression often comes on suddenly. It may be too late by the time you find out.
