I have a 29 gallon tank. So far i have a small yellow watchman goby, medium/large royal gramma and a small pygmy dwarf angel. My water parameters are great as we swapped rock and what not from our 40 gallon breeder so i got a good start to this tank. Im wondering what other fish i should get for my tank and what a sufficient clean up crew would be. We also have a well established 55g tank that my husband manages, so i have decent knowledge on this hobby. I am not going to have corals, i want fish only. Just seeing what your thoughts are!
