Flatworm exit to remove predatory worm?

What's the rock worth? Why not just toss it and cut your loses?

The cost means little to me, would definitely prefer to keep it though, the rock is about 3/4 of a soccer ball in size and has a nice shape to it. If I toss the rock, the worm wins, I don't wanna lose to a worm, too stubborn

How about you put the LR in a 5 gal pail without water overnight. Maybe the worm will come out looking for water?
I like the idea or putting the rock into ro water.

Electrocuting it won't work if it is inside the rock. Electrical charges travel on the outside of the rock only....

Took the rock out and let it sit in 10 cups of RO and 10 ml of coral dip (precision solutions) for 1 hour. Killed 3 bristle worms, 30 brittle stars and 50 baby snails. No Oneone Fulgida. Then shook the rock around in a bucket of NSWdropping off some more dead snails brittle stars etc, and put it back in the tank
It either didn't die and is still hiding, or died and can't flush it out, or it moved rocks overnight and wasn't in there.

Will have a look for it when the lights go out

I'd leave it out overnight or take more drastic measures like that but I want to put the rock back in and not kill off everything as the tank may not be large enough to handle a mass die off of all bacteria, algaes etc.

Since you soaked it in RODI water when you tried to electrocute it that will kill the algaes and bacteria. I would suspect the rock will cause a mini cycle from the die off.
Since you have already nuked the life on the rock then you can try soaking it in 50% hydrogen peroxide and 50% tankwater for an hour or more.
The easiest method is to just leave it out in the rain for a week or more. Then cycle it in a bucket for a month or so. The coralline etc will grow back.

It is the minerals in the water that conduct electricity and not the water itself. RO/DI water is non conductive, ie conductivity or TDS = 0. I have seen people put computers(motherboard etc) in RO/DI water and run them. NEVER MIX ELECTRICITY AND SALTWATER!!!

Glad your still alive.

Cheers,

Ahhh, guess that's why the current readout on the charger didn't change a bit. A motherboard running in water?! Crazy! Just taught me something, thanks!

Didn't see it last night, may give it a few days back in the tank. Will then try to flush the holes out with a syringe to see if dead worm slime comes out, if not it may still be alive. Next step will be flatworm exit, and if that doesn't work, then the rock is coming out for a while...
