Can anyone tell me what I am dealing with here??
 
I initially thought this was ich and was treating as such but after a week and no improvement I took a few pics and blew em up and this is what I now see.
These are bleeding bue tetras in a community tank with angels, clown loaches, corys, angels and rasboas. These tertra seem to be the only ones affected/infected.
I previously had a little swarm of columbian tertas that didnt last a year. They all got black spots and eventually died. Again, only that species was affected....
I am at a loss here.
 
Hello. These may be a type of anchor worm. I would research this subject. There are medications if you believe your fish may be infected with this type of parasite. Salt is likely the simplest remedy, but do your homework first.

Thanks for your speedy reply.
 
Not Anchor Worms for me. Looks more like Dermocystidium. Worms living in cysts under the skin. They’re apparently very host-specific, and like characins. Are they sticking out from the fish or embedded in the skin?


Edit… not worms, but form worm-like spore structures inside the cyst.

They appear to be sticking out.
And yes, they are only infecting the Bleeding Blue Tetras.

Definitely cysts though. Anchor worms are a translucent grey and straight, up to a cm long, and attached to the fish only at one end. These curly bright white ones in raised cysts are dermocystidium.

It's a good chance to experiment and try to find something that treats them.

It's meant to be a type of fungus so salt, Methylene Blue or other fungicides might work. I would put the fish in a separate tank and try different medications. Start with salt because it's mild, and then try Methylene Blue and then other things. If worse comes to worst, you kill the fish. However, you might find a treatment that works.

Unfortunately I don't have a separate tank to experiment on with this. If I use any treatment it's on the whole community. I am little reluctant to expose everyone to more stress than necessary.
I know I really should have a hospital/ quarantine tank but I have limited space and resources.
