Last night while feeding my Yellow Watchman Gobie I noticed what looked like brown smudges on both sides of his face. When I looked closer it actually looks like blood underneath his skin. I have had no rock movement and water parameters are great. The gobie has actually been in the tank for close to three months with no problem and I have not added any fish for the last month. Doe anyone have any idea what is wrong with my little fish? If so, what do you recommend for treatment. Thanks,
