Anyone know what this could be? Air pockets on scales and turning black...
« on: October 09, 2009, 07:20:30 PM »

Hi all, I have had this goldfish for about two years.  He is the kind that has the bubbly head (sorry, I'm not well-versed in fish).  I have been noticing some changes in him and don't know if he's getting sick.  It almost looks like he has air pockets on some of his scales, and a big air pocket around his eye.  The end of his tail is also turning black, very little though.  It's as if someone drew a black line on the edge of his tail with a marker.  Are these things I should be concerned about?  He's still eating and swimming.  Any input would be appreciated, and I can try to take some pictures if that would help.

Check your other post. It could be an indication of an ammonia problem.

I know it's too late but I have just joined this forum specifically to find out what's happening to my fish. He has the same problem as your fish it seems.  He has "bubbles" or clear blisters in his fins. They start out as a colorless blister and then turns black after it "pops".  I don't really know if it pops.  It was a blister one day and gone the next and black the following.  I don't think I have an ammonia problem but I am out of ammonia testers so I guess it's possible. The problem began after we went on vacation and had a neighbor kid feed (ridiculously overfeed) our fish. One died and the second seems otherwise healthy and happy other than for these blisters.  If you learned anything could you let me know?

Take a look at your water quality. Test the pH (should be around 7-8.5), nitrite, nitrate and ammonia.
As the blackening could be caused by bad water. Ammonia for example is very toxic to fish, and may be the cause for this condition.
Or by excess nitrogens, the fish might be over-producing the protective mucus layer, and this might be what's appearing as the "air pockets". If your water quality is good, then you should start looking for a good treatment for parasites, as they are known to bring on such symptoms as well.

Hope your fish gets better (:
