Our new orange shoulder tang is doing something very odd, just wondering if this is a normal occurrance, or if Old Salty's gonna have to set me straight on quarintine proceedures. It looks like he is stirring up the sand, or scratching his jaw or side on the bottom. Not sure what exactly he is doing, just looks very alarming. I don't see anything wrong with his skin, other than the fact he is scratching his jaw up doing it. Does anyone have a tang do this odd behavior?
He has parasites. I have had a few do the same thing. Quarantine is a must! If you need info on setting up one check out Andys thread about his clown with marine velvet.
There are several meds you can use. Problem is catching the infected fish. Second problem is, if he does have bugs, then they are most likely all in your water column. So, a UV sterilizer will kill the free floating bugs in your main tank MAYBE. As for treating the fish, you first have to narrow down what he has and how bad he has it. Then you will find that their are SEVERAL different treatment methods, none of which are a guarantee. Sometimes it is just hit or miss at best. I personally like the fresh water dip and then hypo-salinity, if this still does not work copper is the next step.
If he has gill flukes you can get rid of them by freshwater bath or by just removing them manually.
wet a towel with tank water
hold him in the towel lift the gill flap
if you see some critters attached to the gills use tweezers to crush them then pull them out, CAREFULLY
I personally think the tweezer method is less stressful on the fish (but more stressful on you) than the freshwater bath method.
Tip: A couple shots of tequila before the procedure seems to make the tweezer hand a little steadier.
Jahdiel,
Watch the fish for a while.
When he rubs, does he appear agitated like he's trying to rub off a parasite?
Does he rub the same side every time?
Does he yawn or flap his gills rapidly.?
Do both gills look normal? Does he hold one side open? or keep one clamped?
Does he look red or swollen around his gills?
Can you see any thing hanging out of the gills?
Is his slime coat normal or does he appear white or frosty looking?
Is he eating?
Well after many attempts to treat the unknown, we tried someones suggestion to use a Melafix treatment for a few days. Not good! Needless to say, after 24 hrs treatment he was laying on the bottom with all his buddies looking at him like he was supper. I don't think I will buy tangs any more!
It sure was. All's I can say is, I sure am glad you did not get him afterall. Needless to say I had a big all cry last light when I saw him at the bottom. First my little maltese, then fish and coral , my cat is having a very difficult time, and our big rotties are going down hill. Talk about going to have empty nest syndrome. Oh and our son is getting ready to move out. Man I feel like crying again.
I know how you feel Karen....you can email me anytime.
I had a good old cry cause I had to rearrange my tank last night after a ricordia fell down behind alllll the rock and my new frogspawn was stinging the hell out of my zoa's.....damn thing.....

Glad I'm not the only one.......Karen, so sorry to hear about that tang, I was sure pulling for him. He was a good lookin-fella! I think you can be sure in knowing you did your best to help him. Let me know if there's anything I can do,
