So due to medical reasons, short of feeding the fish daily, the last 6 months my tank has been neglected. Things are getting better and I am working on improving water conditions etc. But what is amazing is the life in the tank now. I have coral which stayed alive. Before things got left alone, starfish, anemones, and arrow crabs wouldn't stay alive even with optimal water conditions. Now I'm finding anemones, I found baby star fish etc. Crazy how things work.
