Yellow Tang sick

[discretekarma]

I have about 12 fish in a 180 gallon tank. All of them are 2" or smaller. I checked all the levels the other day and they all seamed fine. PH 8.4 Nitrite 0 Nitrate 0 Ammonia 0. The specific gravity is high though at 1.026 or 1.027. Should I tank out some salt water and replace with fresh water? This morning my yellow Tang is laying on his side on the bottom of the tank. I thought he was dead so I tried to pull him out when he started moving again. Not much but he was alive. I left him in the net and hooked it over the side so he wouldn't get lost in the 200 lbs of LR. He is still not really moving . The only thing I notice about his appearance is that he is pale and looks like he has a small brown spot on his side, no white spots. I checked the levels again and they are still the same. I've had him for a few months with no problems.

 

WHAT CAN I DO? Why is he sick and the rest of the fish seem fine?

Couldn't say for sure, but isn't that a newly set up tank? That might have something to do with it, although your levels look to be fine. The salinity is not a problem as natural sea water is at about 1.0265. What are the other fish in your tank?

 

Oh, and I'd watch out for putting it in a net. Their gills and the spines in their fins will get caught in the netting and it'll die if it can't move its gills around with ease.

Is he breathing heavy or barely breathing?

I took him to the fish store and they told me that he looks like he might have been burned or stung by something. I'm not sure what would do that but he said that's what the brown marks look like. They said he might have a bacterial infection so they gave me some medicine (Maracyn Plus). I have in a 5 gallon bucket for right now. Anyone have any ideas? Could a Pulsing Xenia sting a Tang? He's breathing fast and heavy. His fins were slightly beat up too.

 

His tank mates are:

1 Bar goby

2 Lawnmower Blennies

1 Tomato Clown

4 small green chromis'

 

peppermint Shrimp

Snails

brissle worms

emerald crabs

hermit crabs

 

Pulsing xenia

buttons

zoas

feather dusters

 

I think that's about it.

 

I'd appreciate any ideas.

could the fish have been injured and then subsequently infected by bacteria? I've heard of flat-bodied fish being sucked up against intakes and pumps and stuff because of their shape...

My Tang is dead.

My Tang is dead.

 

WOW , sorry to hear that. I would be interested to know what cause such a suddent and drastic demise especially when there does not appear to be any obvious predators or water problems?

I'd love to know too. Any ideas from anyone?
