Flashing and Scratching

[Mr.Fish]

My Angels start to show some ick signs.Flashing and Scratching and their colors seems pale, no visible spots tho.They have been doing that for about a week.I raised the temp to 88F.Would that deal with the probelm?
Ammonia 0,Nitrite 0,Nitrate 0,ph 7.5
4 angels
5 cat fish
Thats all what I got for now?

Just keep the temp @ 87 to 88 for 7 to 10 days after the "last sign" of ick. In your case since you don't see spots when they stop scratching & flashing, or if the spots do show up just keep it high until 7 to 10 days after the last one is gone. HTH
