Just noticed this bump on my yellow watchman goby. It 's much brigheter and bigger than is noticable in this picture, but it seems to be a bump from under his skin. The white dot is just one of the many normal dots on its body but it is distorded so it looks whiter, it is not ich.
Any ideas? It has been acting normal. Normal breathing and eating habits. Seems to be out and about and swimming as normal. Not scratching. No other fish seem to show signs of anything.
