thanks for the speedy replies,
first off, its a 60 gallon reef tank with 20 gallon sump under, 1 rio 2100 pump and 2 rio 400 powerheads, with a bunch of bio balls, 15 lbs of Fiji live rock, 3 damsels, (2 black white 1 blue) 1 California Sting ray about 4 inches across 6 inches from tip to tip, my banded shark, and 1 21' Bamboo shark. All of my water levels seem to be ok, (salt, ph, nitrate, ammonia). I have 0 grade sand, the finest the lfs supplied. To acclimate the shark i had it in its original bag for 2 hrs at the top of the tank. I don't know if it is bleeding, thats just what it appeared to look like, its only from its mouth to its gills. As far as physical symptoms go, it hasn't really shown any other then it laying at the bottom of the tank with no movement other then its gills. My other fish seem to be doing ok (routine eating and movement) when the other shark or sting ray bumps it, my shark does nothing. its almost as if he is dead. he did swim away on his own when i got close to him with glass cleaner. I will check tomorrow for garlic guard at my lfs.
I got both sharks this past Monday.
I appreciate the replies, this is my first salt water tank among many freshwater tanks. I know sharks are not for beginners but i am learning as i go and seem to be doing ok.
Btw: i feed all 3 of them live ghost shrimp about 5 or 6 each at a time.
