Thanks,
I felt terrible when their little barbles were looking tattered so got the gravel out as soon as I could but generally they are all healthy and feeding well, pleased they should be ok thanks
I made the same mistake. I had large sized gravel and didn't think it would affect them, but after I noticed their barbels start getting shorter, I immediately switched to a fine sand. They seem sooo much happier now. I feel so bad for them.
