Today I noticed several fish in my 75g Malawi setup diving into the sand appearing to scratch themselves. There are no signs of disease (discoloration, spots, redness, gasping or any other syptoms). They all eat like pigs and seem healthy. However, the scratching is insane as they literally seem to bounce themselves of the substrate. Params are fine: 0 ammonia, o nitrates, 10ppm nitrates. Anyone ever seen something like this? Could it be the beginning of ich? Never seen ich without spots, but have seen this behavior in fish with ich. Aquarium is only a couple months old and was all stocked at the same time. So there are no new additions.
