All my levels are great. My ammonia, nitrate and nitrite are all at the minimums on my test kits. The ph is between 8.2 and 8.4. The spot on his eye looks as though he's "shedding" it? It looks like its falling off. The guy at the pet shpt said it may have been caused when he transferred from their tank to the bag to bring him home. Also said that he was stressed and that may have caused it too. The little bugs are similar to the picture. Same color and transparancy... but not as many legs as the picture. The more I read.. the more I think they are copepods... I hope. As for whether the tank is big enough, I asked the guy I get most of my fish from ( not where I got the shark ) about it and he said as long as I provide a large swimming area for him, he should be fine. So, I have made to large "piles" of live rock in the two back corners of the tank. The blennies seem to love it, with all the little crvices for them. I thank you for your time and look forward to your information.
