i just noticed on one of my neon tetras, there is a small protruding bump inbetween his pectoral fins (on his "chest"). anyone know what this could be? i am currently treating the tank for ich (2 tsp salt/gallon) and its been being treated for just over a week now. his colors are still bright and he is still acting normal.
