This morning I woke up to my ATO failed, salinity at 1.021 and kalkwasser EVERYWHERE I could barely see the fish. Everyone was at the top gasping for air. Water changed 50% to get the kalk out and reset salinity. Then during that process my dottybsck and Midas blenny got stuck in their caves and didn’t swim out. The dottyback flopped herself through a hole in the rock and into the water but has 3-4 bruises on her side and swam into another cave and haven’t seen her since. The Midas blenny was in the cave and I haven’t seen this whole morning. The tank is cleared up and back to 1.025sg. What should I do about the injured fish? Is there a way to help them recover from physical injuries or do I just have to let nature run its course
