I set up this 55 gallon. It is currently cycling and the plants are establishing. I would like to keep a pair or more in this tank. These would be my first Apistos so I was thinking about going with Cacatuoides, however I am open to suggestions. I just want to make sure that this tank is appropriate to keep these fish and also if you think it would be possible to keep more than one pair. Keep in mind that I have a lot of stem plants in here that have not grown in yet. I am going to put a coconut cave in there, or two if you think I can have more than one pair. I may rearrange the stems around the caves which would provide extra cover. Thank you.
