Itchy fishies

[Xavier]

the twins, scraps , and coolio keep doing this sorta off scratching on the rocks. they lean against the gravel then quickly bounce back up as if they've got an itch. I've seen it before but i forgot what to do.

Sometimes it's a precursor to ich. It can also mean that the p.h. isn't right.

you should check your water perameters and tell everyone what they are
