I have noticed that my 2 oscars are occasionally shaking their bodies, fluttering their tails, and scraping themselves on the bottom of the tank and on the rocks in their tank. I have also noticed little white blister-like things on the black oscar (can't tell on the albino). I have only had them for 3 months and this is the first time I have noticed this behavior.
Sounds like Ick and I have been treating them for Ick, but I wanted to see if anyone thinks it might be something other than Ick to make sure I am not treating them for the wrong problem.
I am going to do a 50% water change tonight. Maybe it is a water quality issue. Thanks all!
