So I have a 29 gallon tank with sump. Not a biocube, but a standard tank. I have a large fuge in my sump. Currently I have a pair of clowns and a firefish. I have always wanted a diamond watchman goby. I know how they can cause sandstorms and move corals, but I have been wanting one for the past 5 years since I joined the hobby. This tank was in a way planned around one. Could I add one or would it be too much for the tank. I have plenty of live rock and a lot of bio balls for biological filtration so I don’t think that would be a problem.
