Powder Blue Tang Disease

[Rickyrooz1]

My Powder Blue Tang contracted this clear film on the side of its body yesterday and later on it turned a little brown. This morning I woke up to a dead tang and it looked like there were patches of internal bleeding. Does anyone know what the tang could have contracted? I received it last week from Live Aquaria and it has been in a 40 gallon breeder as a quarantine tank.

I don't know what it is, but good thing you quarantined it. Sorry for your loss.

You said you got it from LiveAquaria. Did you contact them about it yet?

Here is Live Aquaria's reply to the picture I sent.
"Thank you for your reply. We sincerely apologize for the loss of the Powder Blue Tang. After doing some research we feel the cause of your Tangs death was Skin Hemorrhage, which is mostly caused by water quality and stress. We ask you to please email us back with your water parameters just to make sure there is no issue there. Once we have this information available we will be able to assist you further in this matter. Thank you for choosing Drs. Foster & Smith LiveAquaria for your live aquatic needs. You are a valued customer and we look forward to hearing from you in the future."

My parameters were as follows.
pH -8.2 (API Test Kit)
Temp. - 75

Ammonia - 0 (API Test Kit)
Nitrite - 0 (API Test Kit)
Nitrate - 0 (API Test Kit)

Powder Blue tangs and Powder Brown tangs are notorious for dying out of stress... shipping may have been too much for him. If they make it past the first week and aren't sick and are eating they usually will live in my experiences

I'm telling you the bag I got from DD tested pH 7.6 and a salinity of 1.030. Talk about stress.

Imo looks like a ammonia related issue most likely during shipping, did the eyes look cloudy when you received the fish? Did the film look like a mucus coating? Also could have happened during acclimation when fish are shipped ph drops in the bag and ammonia level rises when you drip your water into the bag it raises the ph but also makes what ammonia is in the bag more toxic, what I do is find out what salinity your wholesaler or retailer keeps there fish at match that and when you get the fish float to temp and off they go this is what has worked for me I have tried the slow drip method and imo just adds more stress that is not needed.

Also check the gills of the pb it should be nice and red if pale then likely ammonia related

"Subcutaneous" hemorrhage like that is typically due to septicemia (bacteria in the blood causing physical symptoms). Your tang probable encountered a bacterial species in your QT that it had no immunity to. Add this to the shipping stress any fish will encounter, even those from DD, and you have a lethal combination. So sorry for your loss.
