First post: very jittery, thrashing Angelfish.

[gip111]

First post here and not sure if Angels are considered monster fish but will try...
I am not new at aquarium fish and have kept angel fish for years, but I need help and thought I'd post here. About 4 months ago I purchased 4 small/medium angels and were doing very good, no agression and all ate very well and growing at a nice rate.
Here is the problem, within the last month or so, I can't even get close to feed them, they will start thrashing around, banging into the glass etc etc. Where they used to relate someone getting near them to feed them
has now turned really ugly, they are full of scrapes, dings and dangs, they used to take front stage all the time, now they just hide. I personally never experienced this behaviour before with angels.
The tank is a 55 gallon with some drift wood and rocks, temperature a constant 78-80 f. No other fish but the 4 angels in the tank.
Would love to hear some advice on this, I am ready to give these fish away.
Thank in advance
Gil

the fish are also hiding all the time- not just acting different when you approach. So, check for stray electrical current- via possible heater malfunction etc.

I would really doubt it being a stray electrical current, as it seems that it would kill the fish. You know how you arent supposed to have any kind of elrical supplies touch the water while you are showering or bathing? Its because it will shock you. That will still happen with fish, even though they continuously live in water with electric equipment. It just doesnt sound like it would have anything to do with a heater malfunction. But then again, I really have no idea what it could be though, so dont take me to heart on that one.

I've seen it posted as a problem in here many times with heaters. it's just some stray current, not full voltage...makes fish act crazy.

sorry, my terminology is probably wrong, but seen lots of posts about It happening in tanks.not only heaters. test water pumps too. it doesn't always kill or blow things up.
