Anchor Worm

[Hope J]

Hi everyone! Sorry it's been so long since I've posted, sometimes I get stressed and just drop off the face of the Planet. Anyway, Pandemica has a Anchor Worm I think. I don't have the proper net to catch her nor do I have a big enough bin to put her in for closer inspection/removal of it. I did my first dose of Dimilin X last Saturday and did another one today. My question is: What temperature does the water have to be for it to work? I've been looking online and on the bottle but I haven't found a temperature range and I need to know because we are up and down on weather which makes treatments and water changes difficult. Thank you!

I forgot to add, there haven't been any new fish or plants put in that pond for at least 2 years so I think it came from a frog? They hang out in the pond in the summer.

So Dimillin X interupts the molting process, and there are only certain stages in the life cycle that the worm molts. You need to treat the pond every 5 days for at least for 2 month to get rid of them, because typical life cycle is 18-25 days, and the female once matured can live on the host for 30 days and continuously producing eggs.

Thank you, I didn't know that
Everything I have seen so far says 3 or 4 treatments. Thank you for the information.

The life cycle is faster when the water is warmer, given now it's just spring perhaps treating longer is safer, female can even overwinter on host's body.
Dimillin X is not toxic to the fish iirc.

Do you know what temperature Dimilin needs to be at to work?

I think temperature is only crucial in relations to the life cycle length, meaning, colder = treat for longer.

Thank you! That is what I needed to know. I appreciate your help and will treat for 2 months instead of 1.

what is your water temperature?

what is your water temperature?

As of right now 50° Fahrenheit. I did the second dose yesterday and I know the temperature was warmer because we had some warm days and mild nights. I wanted to do a full water change over 2 days but ran out of time before it got cold again.

According to the reference, they don't mature unless water if 68F, and females start producing at 57F for 16 weeks.
My pond doesn't really get all that warm though I'm having anchor worms so I'm not exactly sure what's going on.

The optimal temperature range for Lernaea is 26°C–28°C. If temperatures fall below 20°C, juvenile Lernaea are unable to complete their development, and at 14°C, females will not reproduce. However, adult females can overwinter on the fish host, producing eggs when water temperatures warm up in the spring.

Found on the same sight you posted

It's getting down to 34° Fahrenheit tonight which is roughly 1.1° C if I have read correctly (probably not), will this temperature break the entire life cycle?

And also getting down to 29°Fahrenheit tomorrow night.

I would say inhibits the cycle. It well continue once the water warms up.

Thank you. I'll treat for 2 months just to be on the safe side.
