Update on fish problems
Hi all
(There is a question at the end of all this 'background') Several weeks ago I asked for help on a fish problem. In short I tried to describe SOME fish with dandruff type appearance, bloody backs, long tail splitting then beginning fin rot symptoms and mentioned a heron hanging around, missing fish, but no actual siteing of the bird at the pond. A pond group member, studying to become a koi advisor came by. Unable to catch a fish the first time I only treated with 2 .1% salt applications and one prescribed application of Melafix and draped a seine net over part of pond for protection. By the time the friend returned in 3 days the 'bloody backs' had dissappeared almost over night. I had wondered about my description as the coloration was a very dark red and I actually had one shubunkin who seemed much redder than the predominately blue it normally was. The fish did seem a bit more active and no further deterioration seemed to be happening. She did scrape the two fish and found nothing except for a few paramecium, although she did disclaim her findings due to 1)not lots of experience and 2)40X scope. I pretty much decided things were okay and it and it was probably just 'spring crud' which was now subsiding. Since then several things have happened. One larger koi was apparently jabbed by the heron as there was an obvious deep puncture (though not completely through) and I had to put him down about 24 hours later. On two consecutive days I also found 1 -5" comet floating with no obvious signs off problems (other than the obvious. This may be totally unrelated to any other problems I have been having. Though I was too lazy to get up at dawn to verify, I suspect O2 deprivation, as the weather has recently turned very warm, I am having some algae bloom and I HAD bunches of submerged plants. I removed quite a few of the plants, but certainly far from all. Since then everything seems to be improving. No more death, all 'dandruff' problems have dissappeared and fins may be repairing already, definitely not getting worse. I would not be writing, except possibly to thank everyone for their help were it not for one concern. And again I may be overreacting. One of the two comets which I 'caught' had a small bump on it's back. At the top of the bump but not in the middle was a dark brown 'thing'. It does not have any particular shape and at least now is not on the surface. My friend said it was not lice, but didn't want to poke and prode at it. It almost looks like a small scrape which has a small brown covering over the scrap. I'm not saying it is a scrap, it just reminds me of a very small scrab over a scrape, except it is not on the surface and appears smooth. This fish is still in the quarantine tank and I have seen no change in it. Perhaps I am just now noticing them but one or two fish in the pond also have this. One I have been able to see several times. Again using my scrap analogy it appears the same (I have not captured it) although the 'scrap' would be one 1/2 inch abrasion follow by three or four progressively smaller ones. These are much narrower than the 'spot' on the top of the quarantined comet. So at long last - does this sound like something I should be concerned about - or just watch and see. I am very sorry to be sooooooo long, but I just never know what to include and omit. The water parameters are constant and perfect and yes Carol I did do 1 25% water change before I added the salt Thanxx Bill Brister - Austin, Texas |
