So I have a 75 gallon tank with the fluval fx4 canister. I don't have lights yet but I will soon. Not sure what sand to do or rocks but working on figuring that out. The fish that I am think are 4 clowns (naked, maroon, full black and white and normal). Will they be fine all being different kinds? I also want some chalk bass, blue green chromis, I kinda want a tang but I don't really wanna pay for how expensive they are and maybe a foxface. I have no idea what to do for a clean up crew so some help that way would be awesome. I also what to do some really easy anemones and corals but I don't know which ones. Any ideas for fish and corals would be awesome!
