other than my pond I have one tank with a mean angel in it who kills anything I

Not unusual behaviour for angels. The only other fish that I have been
able to keep with angels are ones that are also semi-aggressive and that
swim fast. I love angels but after last December's ice storm with five
day power outage where I lost all my tropicals, we've started keeping
fancy goldfish in our 55 gallon tank.
