My son loves oscars and the oscars seem to like him. He has me drove nuts to get the oscar. BUT he just picked up a 2" oscar. As you know they do grow. The 2" is in a 33 for now.
Alright, from someone who has and still is rescuing fish, if they are already in poor conditions, and you are offering a larger, better home for them, money is not an option. I had someone email me saying that they were "in desperate need of help" with their 12" Oscar with HITH that was in a 20-Gallon. They wanted $50, and I could have him. I don't pay people to take the fish that they don't want, and are in poor condition to begin with, and some people just don't get that.
I say he gives them a better life by just giving them away, or it isn't worth it. Just my opinion.
