Okay, I'm afraid a couple of my fish might have ich. I was doing a water change today and just noticed some white spots on my little Catalina Goby and my Clown Goby. From my experience in fresh water, it sure looks like ich.
Parameters are as follows:
Setup is 75 gallon tank with live rock, sand bed, and protein skimmer.
Ammonia: 0
Nitrite: 0
Nitrate: 20pm
pH: 8.3
Temp: 80-82
SG: 1.024
Some other things worth noting:
-I got the Catalina Goby and the CLown Goby from the same tank at the LFS on the same day about 3 weeks ago. So far, they seem to be the only fish affected. They are still acting fine an eating as far as I can tell.
-Both are the smallest fish in the tank, but they really don't get picked on, with the exception of my yellow tail damsel chasing the clown goby every now and then and my yellow headed goby chasing the catalina goby away if it gets too close to his little cave.
-I bought a pearly jawfish about 4 days ago. He dug a burrow in the corner and stayed there until 2 days ago when my boyfriend accidentally scared the heck out of him with a turkey baster. Haven't seen him since. Could he just be scared and in hiding, or could ich perhaps have gotten him too, although I didn't see any spots on him.
So far, my other fish look fine. Is it possible that my other fish might not end up getting it?
Unfortunately, I don't have a Q tank, and it's also a reef, so copper is out of the question. What should I do? I really don't want to lose any of them, especially my pair of occilaris clowns, I've gotten rather attatched to them!
Sorry this was so long, but I figured the more info I gave all of you, the better

Any suggestions or help would be GREATLY appreciated! Thanks,
