I have 2 in my 12' aquaria. One is 26 and the other about 14". As soon as any pellets go in to the tank they are up at the surface hoovering them all up very noisily. They are the perfect large cat as not aggressive at all. They roam with a large giraffe cat and a Pictus. If you have the capacity to house them then you are on to a winner as look awesome
