View Full Version : Nasty parasite pictures - need ID

I had just finished treating the DT with Prazi, and now it is in the first few days of treatment with Cupramine. I had made the mistake of not QT'ing my last fish, a Goldheart trigger. All of my small fish are doing fine and eating, although the large Queen trigger is taking it a little harder.

I came home from work today, tested the water, fed NLS pellets and an algae sheet. I started to siphon off some dead bristle worms, when I noticed a white stringy looking thing about an inch long. I siphened it out and put it in a separate bucket to look at later. Then I noticed that the Goldheart had a similar looking thing hanging from his butt. He swam around for a little bit, and it didn't break off like poo normally would. He hid in a dead end cave, so I thought I would try to get it with the siphon tube, and sure enough, another two inches of it slid out of the fish and up the siphon tube. Three words. Nasty, nasty, NASTY.

I have a USB microscope at home, so I took some pictures of both of the parasites. They were both dead, and their bodies looked empty, but they did not look alike. The smaller one had many little hook-like appendages at the business end, and the larger one had more of a geometric pattern. I'm not sure how much of them were missing, but they seemed fairly intact. There was one in the Queen triggers tank that was mostly decomposed, and two small ones about one inch each in the other tank. Both of those had a reddish-brown color, and they looked more like the smaller one with the hooks, but I didn't get a chance to siphon those two out.

Now, when I first saw the parasite hanging from the Goldheart, I thought of what many people have described as "stringy white poo". I was more that a little shocked to see that it was actually a parasite, and how long it was. The thing is 3 1/2". The fish is only about 5"-6".

The Cupramine is apparently killing the parasites, and the smaller fish are doing pretty good. The Pintail doesn't eat much, but the others all seem more or less normal, and their ich spots are diminishing. The Queen trigger, however, has not eaten in the last two days, and just kind of sits there. I understand that it can affect fish differently, but after seeing those parasites, I wonder what internal wounds need to heal once they are gone. I do have an ammonia reading of .5 from the die-off in the rocks, so I'm sure that does not help.

Last week, I was feeding my fish in ignorant bliss, thinking that everything was going too good, and now everything is a little crazy. I QT'd my fish, but I didn't follow through all the way. I'm making this post to find out what these parasites are, but also as an example of what can happen if you don't follow strict quarantine procedures. Don't fool yourself.

These are still of the smaller one, but with an LED backlight to show depth a little better, so the shots are more blue than they should be.

What ARE those gross things? anchor worms? flukes?

thanks for sharing, really. those are truly disgusting, but good to know about what our fish can come in with.

magnification?

The close-up of the hooks is 100x and all the rest are 40x, I believe. I've seen a picture of the larger one somewhere, but I don't recall what it is.

The geometric one looks more like eggs than a different species of parasite. D: Scary stuff, but amazing photos!

I agree with LukFox, that the geometric shaped thing looks like eggs to me.

Try searching for spiny-head worms, Acanthocephalans. If that's what they are, not too much of a worry because they utilize intermediary hosts in their life cycle, so once the adults die, your fish will not get reinfected unless the very specific host is present (unlikely). For example, the fish may serve as a first host and the second host might be a marine mammal (no whales in your tank I presume?). Fish can be a secondary host, with the primary being some snail or crustacean.

I wonder if the praziquantel caused the worms to release their hold?

I had the same thought, or a combination of the two.

Those things that look like eggs are what the "head" of that thing were composed of, so I think they were more like suckers to attach to a host.

This morning there was another dead parasite in the sand the same size as the large one, and a bunch of small ones less than 3/4" floating in the water. The fish seem fine, except the Queen is a little listless.

Thanks for the info. Thats some pretty ugly creatures and yes your right about chancing no QT

saltyguy51, did the photo of the Goldheart look like what your fish had?

Jay, the parasite did look like Acanthocephalans. The scolex, head part, looked just like what was described as a pit viper shape. One article stated that "the adult always hosts in the intestines, and very little disease has been associated with acanthocephalans infections in fish, although heavy worm burdens would presumably have the potential to cause serious intestinal damage."

Holy moly! You win the prize for having a microscope to begin with! I thought the queen trigger was in a different tank? My only concern was with the queen trigger feeding video of the damsel, was that lfs water that was pouring in first? If so, that could have spread something.

This all started before the damsel feeding. The Queen is in a different tank, but both tanks are on the same sump.

I had the microscope from when my son, Adam and I bred the piranhas. We found that small mites were attacking the wigglers before they could free swim. Most people think that it is a fungus that kills them, but the fungus is a secondary infection that sets in. I was amazed how quickly it would happen. With the microscope, you can see the blood flow through the eggs, when veins, fins, eyes develop. It's really cool. I can take videos, too.

How much does it cost?

I think it was in the $300 range. My wife bought it for us. Here is a video of one day old piranha fry. What you see in real life is way better than what the video shows. You can see some amazing detail and color.

Here are a couple more videos to. The first is a mite sucking the sweet juices out of a piranha egg, the second is a FW rotifer.

Oh no! I think my black percula has that. Do you think prazi-pro will get rid of them?I took pictures but it's not that clear. I just thought it was a piece of undigested chaetomorpha or something but I guess it is a parastie after all.

should I remove all the fish and treat them for internal parasites or is prazi-pro reef safe?

Thanks Jerry...
I did not encounter anything like this with the crosshatch...but it makes me wonder...
