Fish acting weird! PLEASE HELP.

This is what their poop looked like when I got home. I tried to get good pics, but it's hard when they're not staying still.

i wonder if its ammonia or lack of oxygen in the water.

Did you recently put in some kind of lacerock or similar to change water chemisty?

What about pH? I know Cardinals enjoy low pH. When I had a pH crash the low pH loving fish were survivors, including the Cardinals and Angels, and some others not so lucky.

They seem to be doing better
