Red Spot on/in Anus--What is it?!?!

Hi All,
I just did a water change today and noticed that my Chinese Barb has a rather large red spot on/in its anus. Looks kind of like it's coming out, but it's not trailing like a worm. None of the other fish have this as far as I can tell, but it doesn't look good at all. I can't seem to match it up directly to any of the disease descriptions. The fish is otherwise healthy--no discoloration, no strange swimming, no lethargy, fins are fine, etc. What could this be?

By the way, I separated it out but I don't have filtration in the little tank (homeboy is definitely NOT diggin his new digs). If I can save the bugger, I'll get it a new small tank to treat it, or else....

Hhhhmm...the only thing I can think of is camelanus nematodes...I had that issue once. Though you do say it doesn't look like a worm...what you will see with the nematode is a red string...or several red stringy looking objects coming out of the vent of your fish. If you don't get rid of it it will kill the fish and will definitely spread to the rest of your fish.

If it is camelanus then you'll have to treat it with lavisol...which you may be able to find in a feed store in your area..if you have one. It's actually a medication used to treat cows and sheep for internal parasites. I happen to be lucky enough to live near UCONN so was able to get some there. I couldn't find a feedstore in my area that carried any.

Try doing a search on the issue and see what you can come up with on the net.
 
I'm doing some research again (all of the disease/parasite/fungus descriptions I read previously didn't mention a red spot specifically on the anus area), though the situation seems to have progressed. The area that was red is no longer so, but a white string is coming out. It's not red, and there's only one. Hmmm...
 
I've been to a bunch of sites and gone through the disease symptoms. Though no mention is made of redness, mayhaps this be the problem:


Nematoda

Symptoms: Worms hanging from the anus.

Nematodes (threadworms) infect just about anywhere in the body but only shows itself when they hang out of the anus. A heavy infestation causes hollow bellies. Lighter infestations usually cause no problems with the fish.
Short of destroying the fish, which is easier, two treatments have been suggested. First treatment; soak the food in parachlorometaxylenol and give the fish a bath or treat the aquarium with 10 ml per liter. The bath should last for several days. Second treatment; find special food containing thiabendazole as a nematode (threadworm) cure and hope the fish will eat it.​

I'm wondering if a salt dosing might be in order. Otherwise, I'll do the chemical thing, something like this:

I'm wondering, though: should I treat the entire tank?
 
Personally I recommend having a shot at it with praziquantel, I hope it's available readily there. A single treatment of 2mg/litre is ussually effective in wiping out every worm in the tank, although I'd be inclined to perform a secondary treatment about 4-5days later. It's quite harmless to fish and wont effect the biofilter or disolved O2 levels, so I wouldn't be worried about treating the whole tank.

Following treatments I've done in the past on fish, the bottom of the tanks has often been littered with dead threadworms and it's simply awesome at clearing skin and gill flukes too. I haven't used it before on camallanus sp. worms, but I would suspect it'd be quite effective on them also.

That sounds like a pretty good solution--I'll see today if my lfs has it in stock. Much appreciated!
 
Let us know how you go, if it's not available at an lfs, you might have to order it online or obtain through a vet (Droncit Cat/Dog dewormer (or equiv, just make sure praziquantel is the only active ingredient, crush to fine powder and do your best to dissolve it in water before adding to the tank.).

8mg/gallon will give you just a tad over 2mg/litre, dosage isn't super critical as long as you have a minimum of 2mg/litre, you can safely go up to 5mg/litre although it's not really necessary.

Did someone miss my post ?? :D


I have experience with camelanus nematodes and the cure I used which did the trick is lavisol. Straight Lavisol....if you can find it. Call your vet and ask them where to get it and tell them what you need it for.

I soaked the food in it and I also treated the tanks. It doesn't harm anything, not even the fish but you do have to catch it before they get very heavy with them. I had two fish that didn't make it...both had a heavy infestation...crops of them coming out of thier vents...it was nasty. I had gone away on vacation and came back to it.....but the others made it fine.
