New to saltwater aquarium keeping and made the mistake of not investing in a quarantine tank. I noticed a few of these leech looking things on my goby and tried a fresh water dip and the little buggers didn't come off, so I went to my Lfs and bought some prazipro and dosed my 55gallon tank. But within a few days the goby kicked the bucket after refusing to eat and being very lethargic. After that I cleaned everything, the substrate, rinsed rocks, cleaned powerheads, and my filter and replaced its media and did a huge water change. That all occurred last month, a few days ago my clownfish had the same things! And then I noticed they were on some of the rocks in my tank. I don't know what it is, and the prazipro isn't effective enough and they've seem to be taking over my tank.

First welcome to R2R,

.

Second awesome job on the image.

Lastly I moved this thread to the Fish Disease Forum for more eyes on. I am have no idea what parasite that it and I am not surprised the fish unfortunately died, but I am surprised a freshwater bath had no effect.

Fish leech.. @Humblefish

Arthropod parasites.

bios · Dec 20, 2016

Family piscicolidae
Oviparus life cycle 30days up
Possible treatment:
organophosphates
Green malachite
Hospital tank
Dry rock to kill egs

bios · Dec 20, 2016

Use of organphosphates must be done only from personal addict as they are extreme toxic
Also green of malachite as above
Other way remove they manually if is possible by anestheting the fish and treat injuries with antibiotic

Personal addict i traduce bad

Wow.. Just wow...

Great job by Bios for identifying the culprit. The only treatment I can find that is supposed to work is a Formalin dip. As far as clearing it from the tank, I have no idea.

But Bios seems to know what he is talking about and a tank tear down and dry out may be what is needed. Not sure if they will starve themselves out over time if the tank is left fallow or how long that would take.

Welcome to Reef2Reef, just wish it was under a different circumstance!

FYI, apparently both cleaner wrasses and cleaner shrimp will eat these guys and can control the population.

I believe @bios is correct. Do you know if Dimilin would work to eradicate the eggs on this family of worm?

Also, let's ask @Lionfish Lair for her take on this.

I figured I would have to tear down the tank and dry it out but I have two fish left, and I'd doubt anyone would take them with the possibility of them having these worms. I also took apart my hob filter today and they were in there too. I appreciate the help!
