Sick Angels-New Fish Mom

[Danielle L]

Hi Everyone! I am a new fish mom & have acquired a 125g tank when my fiance moved in. I bought many xlarge Angels over the last 2 months & have lost about 5 ( not all lost or bought at once). I have 7 left, along with an elephant nose, a couple Glo fish, 4 Cory Cats, 12" common pleco, 5 "golden bristlenose pleco & an 8" & 5" Goldfish, 1 butterfly (lost one last week) & 2 Rainbow Tetras. They all seem to be getting along well,but I keep getting Ich,mostly on the Angels. I've been treating with the blue liquid Ich Guard & The All-in-one Fizzers,along with increasing temp to 80°. Also added some Aquarium salt. PLEASE HELP, DON'T WANT 2 LOSE ANYMORE ANGELS......need advice!!
