Ok, well I am taking yahoo answers advice for my fish LOL?

Hm, I haven't had fish in a long time. What I did back in the day was just introduce new fish whenever, except with the more aggressive breeds like betas and goldfish. What I would do, if I was uncertain, is to introduce the fish when you are home for the day and keep your eye on them. If there is problems you can take him out and put him in a temporary place until you can make your long term setup. It it works, than great, if not you will have the nuisance of the temporary setup to deal with. I would think that those fish should be fine.
