A short YouTube case presentation (Case 177) by Gerald Bassleer about a wild-collected freshwater dwarf puffer (Carinotetraodon taravanchoricus) suffering from encapsulated trematode larvae in the gills (referred to as metacercaria/petacercaria). The video shows clinical signs (skinny fish, clamped tail, respiratory difficulty), grossly deformed gills with visible capsules, and microscopic confirmation of worm larvae inside capsules. The speaker states there is no effective treatment to remove these encapsulated larvae and recommends improving husbandry (water quality, food, reduce stress), supportive/functional foods to boost repair and immunity, and considering antibacterial treatment for secondary infections. The presenter also references his books and Patreon for further training.

Hello, dear aquarist, welcome again to my.
Case 177 about a dwarf puffer fish.
Yes, a freshwater dwarf puffer fish which.
Is sick from encapsulated worms in the gills.
So watch my videos, which I show you in my PowerPoint and that you might teach you some lessons. What can happen with fish collected from the wild, like this Carinotetraodum taravanchoricus. Wow, what a beautiful name. With encapsulated trematode worm larvae called petacercaria in the gills. Details you can find about fish diseases.
Yes, in my books. And the link is below in this channel.
And the Carina tetraodon pufferfish.
Here you see them swimming and you can see some are very skinny.
You can see it in the back. You can see it here, this fish.
Here, this fish with clamped tail laying on the bottom, wasting away.
Yeah, that's a few losses we seen.
In the couple of weeks after arrival.
And we examine and we tell you.
What you can do about it.
Because we found in the gills those capsules.
Look, gills are deformed. There are capsules inside.
And we go to a higher magnification.
We see in the capsules that are inside worm larvae.
And those worm larvae taken away healthy.
Guilt tissue inside are in worm larvae called metacercaria or digenetic trematodes. Worm larvae. And they destroy partly of the healthy.
Guilt tissue, of course weakening the fish, making this respiration in difficult matter.
That is not doing so perfectly well.
Typical for wild fish who are living in the wild and have no hygienic.
Measures and can easily be infected by little larvae that come into inside the world by food or by the water. Your actions that you can take is.
For the ones which are not so.
Badly infected to improve the conditions.
Good water, good food, avoiding stress and.
All the measures you can take to.
Give the best possible possible opportunities for the fish.
So far I know there is no.
Treatment to destroy or remove these encapsulated worm larvae.
Some people think they can use anti.
Worm medication, but that does not penetrate the capsule or inside. It's the worm and that medication cannot go inside and you cannot scrape off the worm larvae.
Try to help the fish with a.
Functional food that helps in fish repair and improving immunity.
Check with your supplies.
Maybe an antibacterial treatment is needed because.
Sometimes there are mixed bacterial infections also occurring because of the weakening of the fish. You can get secondary infections.
Things I teach in my books and.
Those are available online. I hope you purchase them to become a better trained aquarist or become a.
Good fish doctor and get training at my Patreon channel. So this was a case about a.
Nice fresh water puffer, but didn't look.
So nice, but was pretty sick.
So check for my next video.
Coming up, video 178 will be the next one on another specific fish disease. Thank you for watching.
