I maintain an 8’ 300 gallon system for the local scool district. We have sucessfully kept a White spotted Bamboo and a Coral Catshark for three years. The Coral Cat dropped 15 egg cases and we hatched 4 of them. In the tank were Pacific Blue Tang, Flame Angel, 3 Bluegreen Chromis, 2 Pajama Cardinals, Flamefin Tomini, 2 Kupang Damsels, a pair of Clarkii, and a Starcki. The Coral Cat fell victim to an infection about three months after laying and the Whitespot outgrew the tank and was rehomed to a zoo in Louisiana at 28” in length. It can be done but unless you have a really large 8-12 ft system they will outgrow in2-3 years depending on start size
