Can anyone tell me what this is. I thought it was sand on the fishes body because I was given 2 1600gph powerheads for XMAS. They are very strong and blew much sand around. There was no storm just the sand in certain spots were forming hills. So I pulled one out and the hills have stopped. I also did a 10g water change yesterday which is when I noticed this. The fish is still very active and eating.
Thanks
