So I have my new tank and its been on for like two months now (maybe) all of my numbers are fine and the fish are doing good. I recently started to add coral. The leather is doing good so far. The torch I purchased yesterday along with my fire shrimp (huge shrimp) and a hammer coral. the torch isn't really out and about and is half out. The hammer is half out too. IDK if the hammer will survive TBH and the fire shrimp just dies a few hours ago. My dang Purple and Yellow tang were being annoying and kept on putting their bodies on him. Could that cause him to freak out and die? also should I do a water change even though my levels read good? I dont want to make a large purchase of coral if this is going to happen to the other ones. Been there done that and nooo thank you. Should I dose? I know I have a few Questions in one thing but I was hoping for some answers.
