I am very new to keeping cichla, I have mine in a 90 gallon with an oscar. I got te cichla the other day and he is 6-7". He was sold to me as wild but I doubt he is. (how do I tell?) I am working on getting him to eat frozen instead of live food. I was wondering if anyone can give me an ID on him because he does seem to look like a monoculus to me but I am inexperienced with this wonderful type of fish and am struggling to ID it. I do however know how to keep the fish healthy, no problem there, tank is cycled and gets a 25% water change at least twice a week so nitrates stay below 20ppm. I wil be upgrading to a larger tank this summer and was wondering what would be a good height for the aquarium as I will have one custom made. On my 90 gallon it seems like a waste to have 24" high is there is only 18" width. Also, the cichla likes to hang around the heater and output for the filter facing downwards almost as if watching the other fish, is this normal? The oscar hasn't quite warmed up to him yet but he is much slower than the cichla so there doesn't really seem to be a problem there. Thankyou for your answers in advance.
