HELP a disease question!
Hi all,
I have a disease problem breaking out in one tank and I need help. The
fish in question are breeder hi fin swords -- third generation aquarium line
bred and big and nice. This is the parent tank and my entire stock right now.
The disease looks like one of the protozoa/parasites one sees on pond raised
livebearers. It started about 2 weeks ago. An old female showed it. It looks
like very big, clumpy ich on the body and fins. The fin form looks like a
soft cyst and the body form looks like it breaks out from under the skin. I
would say they are about 2 - 4 times the size of ich. It progresses slowly
and never totally covers the fish like ich. It is on one of my younger red
velvet females -- one I had real hopes for too! I have tried Neosulfex
(neomyacin and 5 sulfur drugs mix), Livebearer, a formaldyhide, copper
sulfate and malachite green mix by Aquatronics and flubendazole. Nothing
seems to stop it. Does anyone have any idea what this is or how to stop it?
The water is moderately hard and alkaline. There are a dozen 5 inch fish
in a bare 55 with two large potted swordplants, najas, a big box filter, an
airstone and an Eheim 2226 professional. 75% water changes every week or two
at the most. Food is live daphnia, frozen bloodworms, frozen brine shrimp,
live baby brine, Hikari micropellets, freeze dried bloodworms, live
blackworms a few times, live adult brine shrimp, Ocean Nutritition flakes,
microworms and other flakes. Mostly the meaty foods though. The only fish
introduced were some fowleri and erhardti corys about 3 or 4 months ago. They
had been in my tanks for 9 months with other fish and no problem. There are
some sterbai in there too and have been there for over a year and a half.
There are snails in the tank. No salt in the water. Temperature is 75F.
Raising it now to 80F. all other tanks of fish with the same diet are fine --
killies and swords.
Let me know what you think as soon as you can.
