I had my Oscar fish for about 2 years now- he used to live with couple sharks and pleco-but was too aggressive on them and eventually they died. Now I'm moving in a month and want to get abot 75 or 95 gallon tank, will this be a good time to introduce new fish to the tank, and if yes-which kind should I buy? In the pet store they told me that I can't have any other fish
because he's too aggressive_ but I thought that there might be a good chance as he will be in a new tank(environment) as well. What should I do?
