I brought home a Cleaner Wrasse Saturday. He had been swimming around alright but mostly hiding when it saw me come over. Today he has been swimming in circles and has this redness on both sides. What can I do for him?
There are not any Ammonia or Nitrites in the tank. This is a 20 gallon QT I have it in.
