Something wrong with Yellow Tang? <<< Pics Inside>>>

[ImprezaSTi]

This is really weird, I think something is wrong with my yellow tang but I have no clue what.

My yellow tang is breathing heavily at around 10 beats in 5 seconds. He also swims erratically at times, as if he is trying to break the glass, or use the glass as a back scratcher. It makes me really scared when he does this because it looks like he is going crazy. There is no visual sign of any parasites and he eats like a pig.

Params are good. Ammonia, Nitrite, Nitrate are 0. Salinity 1.025. Temp 78-80. All other fish, corals, and inverts are looking good.

Is this normal...? Or if this is a disease, what diseases can cause this? He has been like this for the last month since I have brought him back from the LFS.

Any advice is welcome!

Impreaza,

By extrapolating your fish's repsiration data, it works out to around 120 beats per minute (BPM). You might try counting for more than 5 seconds (if the fish will hold still) to get a more accurate count. I've worked on a project that tried to use fish respiration rates as a measure of their relative stress levels. I have data going back over 20 years, but it is difficult to sort. I did pull up some records for tangs and 120 bpm is a bit high. Normal for that water temp. and size of fish should be around 70 to 90 bpm, but I did have a few "active" tangs that went as high as 130 bpm and were still considered "healthy".

I've heard (but not seen first-hand) that hyposalinity can cause hyperactivity, but that is obviously not the case with your fish.

In looking at your fish's photo, I see a moderately skinny fish, with a bit of a pinched belly, but I've certainly seen worse. Is it still feeding well? If so, increase the "browse" it is getting. In the picture, the fish's myomeres are really standing out (the muscle bands on its side) but that is probably a function of the camera flash.

Sorry I can't tell you why the fish is so hyper.....

Sounds like it might be overexciting itself by its reflection in the glass.

Thanks for your input.

I tried counting his heart beat for 30 seconds a few times. Came out on average to be about 110bpm. I am very glad to hear that this could be normal, as I originally thought that he was breathing way above average rates.

Compared to how skinny he was at the LFS, he is looking a lot better now. I am slowly making him fat, feeding 2-3 times a day of either bring shrimp, Formula Two pellets, some sort of flake, or nori. And yes and the tang does look a bit better in person than in the pics.

Sounds like it might be overexciting itself by its reflection in the glass.

It does seem like that could be what he is doing.



Thanks for the replys !!
