That width is a bit of a problem when dealing with cichlids. Those Dempseys alone will most certainly need ALL of the room in the tank as adults -- they will need more in the future to be honest. A 55 gallon has a 12" width, which is pretty tight itself, but it works. 10 1/2" for a fish to turn around isn't enough for a JD. They can easily reach 7-8", and have been seen at 10". I'm pretty sure most would agree.Twisted0liver;2615448; said:My Tank size is 40.9"L x 10.6"W x 20.3"H
Can you get a larger tank?
