Need help! restarted my reef tank about two months ago. Tank is fully cycled and I wanted to do everything right this time. I set up a quarantine tank and put a pair of Clownfish in with Coper Power at 2.5 for 33 days. I was going to follow-up with Prazipro but after the 33 days everything looked fine so I elected to introduce them to the DT. While the clowns were in the quarantine tank they always stayed at the surface. I though this was due to lack of hiding places. After I introduced them to the DT they continued to stay on the water surface, they eat good but do not swim in the rest of the tank. Right now the only thing in the tank are the 2 clowns and no other corals or Invertebrates. Should I treat the whole tank with Prazipro just in case they have it? I tried to get them out to do a fresh water dip but could not catch them, too much rock work. Any recommendations would be appreciated.
