I have a 15 gallon innovative. Cycle completed a week ago and I’m planning on adding a wrasse soon. So far I have a photon clown in the tank so I’m not sure that I want a possum. I really like the white line possum but I feel like I want a little more diversity in the fish department than two clown looking fish. I’ve been thinking a pink streaked wrasse. I use to have a six line in my old tank who had a great attitude and temper but after doing some research I feel that he might be needing more space than that 15 can provide. Mind you I’m probably going to keep the stocking light on the fish. It might be it at the six line and the clown. Maybe some type of goby or a red tail damsel down the road but not for a while. Any other options besides a six line or the pink streaked?
