hi i have a 15 gallon jbj just using jbj ato, return pump for flow and some live rock work and corals. I currently have 2 gladiator clowns, 1 cleaner shrimp, 3 astreas, 3 nassarious, 2 ceriths, and 1 tiger conch. I had a RG but it died and dont want to try my luck with another one. Im leaning towards a yellow goby and want that one display fish. Of course cant have my favorite fish(CBB) but want something similar or not the same color as the clowns. Ive debated a type of wrasses, like the possom but i dont like the red over taking the clowns. Can i get away with a type of angelfish? Or just stick to the 2 clowns get a goby and a wrasse and be satisfied?
