Just thought I would share this. My red wolf fish kept jumping constantly and banging his head and face on the cover causing damage . I added floating plants, put bubble wrap under the lid and lowered the water level. None of that worked. Then I saw a YouTube video about a shop owner that noticed when ever he did water changes, his red wolffish would jump like crazy over and over. He determined it was the splashing triggering some type of instinct. So I raised my water level almost all the way so the HOB doesn’t splash at all. It worked. He immediately stopped jumping and is exhibiting natural behavior, like lurking in the floating plants for example, but no more jumping. He’s almost completely healed up now as well. Just thought I would share this in case anyone else has the same problem
