I’m bringing this topic back up since I’m going through it now…. I have a yellow belly hippo that finished qt on Thursday night and has been in an acclimation box since. So 3 days now. How long do you think he should remain if at all?
Tank mates that are questionable are a purple tang that is the boss, a bristle tooth tang, foxface that’s super calm. The tank is a 180 gallon.
The last fish I introduced was a copperband several months back. After a few days in the box I released him and even though not one fish cared while he was in the box, as soon as he was released the purple tang made sure it knew who was boss. For a week or more it was nerve wracking. This go around, same story. The purple and others don’t seem to care, but I anticipate some roughness upon release.
