My 2 Angel Fish!

Question
I have two angel fish.  Gold and marble.  In the tank with them also are a beta and two other tropicals(small) and a plcostomus(sp?)  My larger angel fish keeps chasing the other one around and pecking at him.  How do I get the larger to stop or should I get a different fish?

Answer
Whitney,                                                     I would like to know what size you tank is and how long you have had your angels from what it sounds like they are relatively new. You may have 2 males. If you had them for awhile they may have become territorial. Your betta if your tank is small tank is small likes alot of territory. Please let me know this before I advise you of what to do next... Thank you.Tina
