I have had this tomini for about a month now and he is an absolute pig. When I got up this morning I noticed he had a white spot on his nose. It kinda looks like he scrapped on a rock maybe. I added a foxface last night and the tomini has been pretty interested in him, so could them chasing eachother cause him to get scratched some? Or should I be more worried of a disease. After I noticed it, I fed the tank and he ate more than anyone else.
