Clear Bubbles on one fish

[Spanishearl]

I have a tank with plenty of Corydoras Paleatus, they've all lived there for over a year. I've been fighting with Ammonia in it for a couple months now, and have torn it apart looking for the source, can't find anything and the ammonia was fine before. There are live plants in the tank, and I did have a bout of BBA, and that might have been the cause of the ammonia as I treated with Flourish Excel as directed but ammonia spiked right away, and hasn't returned ever since...

Anyways, I just noticed one of my females has large clear bubbles on both her underside, and along her dorsal fin. She moves about fine, is active, and eats well. Shes ugly, but that's another story.... These bubbles are new, but I can't get a picture for you as they all enjoy the plants enough to hang out in them... I'll try to get a pic, but it might take some time.

Anyone know what this might be? None of the others have this, and aside from a couple SAE's being added a couple months back (I tried natural before chemical to rid myself of the BBA), nothing has changed other than the ammonia never dropping since the excel was used...

any way you could get a pic. cories lay clear eggs, but if they've been on her for a while thats probably not the case. how long has she been like this

I know it's not eggs, and this has just started. I didn't see it on her yesterday during the water change and she's pretty unique being as ugly as she is...

I bred these cories from three originals, and she's from the third batch they created. I'll try to get a pic tomorrow as the light is out now.

Are thye just bubbles?When i change the water in my fish tank, the bubble that are gassing off sometimes attach themselves to the fishes slime coat.

When you put something or you finger in the tank do you get bubbles all over it? Are there bubbles in their faeces?

I read that these signs could indicate gas bubble disease.

Not sure about gas bubble disease, do you have some more info?

As for my own experience, in some cases after an injury has healed on one of my Corys I seen clear 'cysts', or bubble develop under the skin. Over time these color to the same pigment as the surrunding skin, and eventually (4-5 months) have re-absorbed ... That's been my experience with these (just Corys)

My camera isn't the best, so this sadly is the best I can do until I get a new one. Because the photo is grainy, I've added arrows to point to the bubbles.

No bubbles form on my hands when in there, and she is the only one affected out of many many fish

There are more under her as well

From the pic, they don't look like bubbles, more like little capsules. Have you tried pulling her out of the water to have a look and see if they pop?

"Gas bubble disease is not caused merely by air bubbles in the water, as the name might lead you to believe. It is caused by oversaturation of dissolved nitrogen gas in the water. Standard airstones and water changes don't harm fish by putting bubbles in the water. Pump, fountain or filter failure, increased temperature or excessive aeration, however, could result in this sometimes fatal occurance.

It is similar to when a scuba diver rises up from deep water too fast, and the change in pressure causes the "bends." The water (in this example, that which is within the bloodstream) is forced to contain more gas than it can normally hold, which causes supersaturation. When this difference between gas pressures occurs, the gas seperates too quickly out of the bloodstream, leaving gas bubbles behind.

Symptoms:
Fish affected by gas bubble disease may have visible bubbles under their skin/scales, or in their eyes. Or they may simply act sick if the problem is internal where you can't see it.

Solutions:
Stirring up the water may help hasten the degassing of the water a bit, but it doesn't do much for your fish at all. Examine equipment: if you have a submersible pump, be sure it's not sucking in air: be sure it's covered sufficiently with water. Equipment that is pulling air in with the water will cause problems."

If you want more info, I have a book which explains it very thoroughly

These are giant bubbles on the surface of the skin. I can attempt to grab her, but it might mean uprooting the whole tank again as they love to hide in the plants, and it's thick with plants...

Popping them on purpose before knowing what they are concerns me, I know I have a lot of fish, but I'd hate to cause her more distress and possibly kill her... I'll try to get her out first, and see if I can get you a better photo...
