I've currently got a 53 gallon which is 4x1'2"x1'2" I'll be changing in a few weeks waiting for it to be built and I'll be changing to a 125gal. 4x2x2

I've currently got 2 electric blue ram cichlid's but I've seen cockatoo cichlids which I think are cool and not see many about just curious to whether I can add them to my set up or not wouldn't be for at least a few weeks after the new set up had arrived due to will be running a new filter on it but using existing bio media in the filter
