I recently won a tall 20 gallon tank and stand in a raffle. It is a Marlineland half moon. I am currently in the process of cycling the tank (fishless) from instructions I got on various web sites. I REALLY want a marble angel fish. I have been trying to do research on what other fish I can successfully keep with my angel. One fish store said that having only one angel fish in the tank would be fine. Another told me that they like to be with other angel fish and wouldn't do well as a single. Some web sites said NEVER keep angels and gouramis together as they will fight and pick on each other. That site recommended platys and mollies would get along fine. Today at Petco (went to look) a woman said the angel would eat the platys and mollies and to get gouramis!! She said she was an expert (very insistent) I am SO confused. I realize my tank is small and angel fish can grow to be a considerable size. If that means I can have only 1 or maybe 2 angels only in the tank, I am fine with that. If I can have 1 angel and a few other colorful fish that would be great too. Any advise would be GREATLY appreciated. I had a 10 gallon tank years ago so I am not a complete novice. That tank was pretty successful and even had a baby swordtail born in the tank which reached maturity. I did have gouramis in that tank as well. Everyone got along fine. I have always wanted an angel fish so it is important to me. Thanks.
