Emergency!! Need Help Now!

Ich can exist as a low grade infection. meaning that fish exposed to ich can build a tolerance to ich.
the ich can exists and when the opportunity happens(new fish, stressed fish etc) it can bloom into a heavy infestation.
that's t one theory used to explain how it 'stays in the tank'.

Am I correct..you have tiger barbs with angels?
 
One of my tiny fry was flashing.
I am returning my 6 Danio, 4 tiger barbs 3 guppies and most likely the 3 angels.
1 barb died ad today one of the angels did too. one guppy is in good health, all others arnt, so they all goin back. no more guppies, i'll stick with the bigger livebearers, they seem more stable and hardy
 
yes i do, but since one angel died, i separated the angels in the tank from all others. it's weird because there were 2 angels, marbled and half gray that used to swim together with no fear. the yellow always hid and has it's tail bit off. the one who died is the half gray, while the other two seem to be fine. one of the barbs is still covered with ich, other two are clear. angels still have some ich too.
