I recently got a 150 gallon aquarium but I have no idea what fish to get for it... Something at least 3-4 inches would be nice it has to be colorful because of the fact that its staying in a daycare. We don't want to have anything thats so aggressive that it'll kill anyother fish we keep with together. We want more than a couple fish so nothing extremely large. Also since there are three of us doing the tank one person wants to get shrimp so that kind of limits what we can have so any help would be nice. Goldfish are a no go because of the fact that the director wants different fish not stuff you'de see in just about any old tank.
