Hi all, I'm new to the saltwater hobby. Got my first 29g tank for Mothers Day. I have live sand and live rock. My only occupants are a diamond damsel, yellow tail damsel, emerald crab and four small hermit type crabs. I had the brown algae come and go from my tank, I just did a partial water change yesterday and cleaned the tank. I am going to check my ph, amonia, nitrate and nitrite levels to make sure all is well. I have been reading all the posts and my mind is on overload. I would like to get a couple new fish and maybe a serpent starfish. Any suggestions or helpful hints?
