mine scratch a lot as well, did you put any salt in the tank? check for
raised scales, or white spots, it may be a parasite, but I find if I do a
water change and forget to put in salt, they scratch a lot more.

Help! Alot of my small Malawis have started to scratch themselves on the
sand. They seem to be trying to scatch their gill areas. I have checked
the
water parameters & all seem OK. the pH is 8.0, gh 6, no2 0, no3 10. The
kh
is rather high at 20. Could this be the problem?

Can anyone offer any advice on what to do?

tia,

Dee
