Good - As long as he is not looking stressed (more stressed). Good luck!!!I see many advantages, but I could be wrong. First, he is not glass surfing like a maniac. When doing that, he is spending energy while not ingesting food to replenish what calories he is losing. In the breeder box he is forced to rest.
Second, he doesn’t have to look for food as it will be placed right in his face. I have never seen him even look for food.
Third, he looks pretty beat up and I can’t know for sure if one of my fish is harassing him. Now he is safe.
You may be right though and maybe he needs to be let in the tank to settle in, but he’s been in there for 8 days already and he is not adjusting.
I’d like him to fatten up and heal before I let him go. He’ll be monitored frequently.
