So my tank is now up and running ( Thank you for all the help) housing a emerald crab, nassarious snail, a baby watchman, and a firefish. He hides a lot which I didn't really know even through the research I did so I would like to get a small clown or something but I'm just worried about the bio load. I didn't have anything spike since I put them in. I do water changes every 2 weeks. Just looking for opinions tia
