Piscicolidae Worm

Are Piscicolidae Worm contagious? It also seems formalin is the best treatment for them?

I have no firsthand experience with those, but I do know they are leeches which can reproduce on or off the fish host.

Basically eggs are laid and a hatchling has ~ 1 week to find a suitable fish host for itself.

A 45 min formalin bath (followed by transfer into a sterile QT) is probably the most effective treatment: https://www.reef2reef.com/threads/formalin.290925/

If I read that right one week fallow will take care of everything? I'll treat the fish and qt everything else for a few weeks of observation.

One formalin bath will kill all the leeches on the fish. But you'd need to go fallow in your DT for 1 week to ensure any leeches "off fish" have starved to death.

BTW, which fish are you finding these on?

Ok that's what I though. It's on my broomtail wrasse. There is only one leach right by his mouth. It's kinda strang as every fish in the tank has gone through qt. They have all been in the tank now for about 2 months with nothing popping up. Nothing has been added to the tank in that 2 months time. Also should I formalin bath all the fish? Are any fish especially sensitive to formalin.

Also wanted to ask are these life threatenthreatening? It's hard to see but it at the corner on the right side.

I was able to get a better picture.

I did the formalin bath yesterday. Were theeaches supposed to fall off in the bath? They are still attached. I did 12 drops per gallon. The wrasse is doing great super active and eating great.

Wow. Can you post pics?

 

[cody hendrix]

It still look exactly the same as pics above.

 

[Humblefish]

Need to pin down exactly what this is. I'm thinking Dactylogyrus trematodes. See pic below for comparison purposes and let me know what you think...

It very well could be that. If it's that what would the treatment be?

Formalin should work on those. Which product did you use?

If it can withstand 37% formaldehyde, I would try dimilin next. Nuclear option would be De-Los (Dylox 80); but that stuff can be dangerous to use on fish.

 

[cody hendrix]

I used quick cure. Should I just try another formalin bath before I start using stuff eve stronger?

What the heck is dimilin?

So, there's some question regarding the % of formaldehyde found in QC: https://www.reef2reef.com/threads/woke-to-a-dead-clownfish-today.546252/#post-5630949

Dang, can I just use more of the qc in the bath to up the amount of formalin?

Problem is QC also contains Malachite Green and that is not something you want to overdose.

Ok then so what's the best option at this point?

Lets tag @mikeyn and ask for clarification regarding the % of formaldehyde found in Quick Cure. And whether or not it can be safely overdosed. He works for Fritz.

Ok thanks

Ok so I woke up and now the leaches are goon. They like melted away over a two day period. Just as an fyi. I did go ahead and do two rounds of prazi as just a hope But now I found these Mark's on him. Also he doesn't seem to be as active as he once was. Still eating like crazy though. But tends to lay on the bottom of the tank. more now. There were never leaches where these spots are.
