So I have read a ton of threads on several sites and am still confused. I currently have a 220 CA cichlid tank and am thinkin about getting rid of the cichlids and doing a Ray tank. Is this tank big enough? I don't know if or when I would be getting a bigger tank. Filtration, light, substrate, etc isn't a problem. Idealy I would have a Ray and a Arrowana together as the only only two occupants but, like I said I have been reading way to many conflicting opinions. Please, only those with experiance reply.
