It wasn't a form of punishment. I separated the fish in order to reduce the stress it was causing the other. I know he's just acting on instincts. It was a temporary solution to the problem. My permanent solution was finding it a new home, which I did 3 weeks ago. The move was delayed because of ich. He didn't show symptoms of ich, but I refused to give him up until I was certain it wasn't present in any fish. I was trying to be responsible in that sense... The person was willing to take the fish sooner, but it's an irresponsible risk to take. I wouldn't allow it.
I am not trying to be irresponsible or careless. I was prescribed Adderall a month ago and it's been messing with my mind and visual perceptions. I'm debating on whether it's really worth it or not. Doctors should never prescribe it to children. It's a very nasty drug.
