The only way i have had anything work aganst aptasia is if you inject it right into them.

Thanks for the helpful tips everyone. I wonder if the heat from the hot water will be enough to 'cook' them off. I used a syringe early this morning but because I didn't have a needle for it I just basted the hot water over the rock surface where I had seen the aptaisia. By the time I put the rock back in the tank it was hot to the touch and I haven't yet seen any aptaisia on the treated surface...

Hopefully that did the trick.
If it doesn't though, I may try feeding joe's juice to them as was described. It sounds kind of fun to do it that way...

I have a wack of fugly polyps you could do that too for me Chad..:razz: :razz:

Update,
So far no sign of the aptasia!

i gotta start workin on mine..my tank is over run by them.. saw one the size of a toonie the other day!

Yikes! Be careful that one of them doesn't swallow one of your fish...
The hot water worked really well. I had a fist-sized rock that I was treating and I used a syringe to squirt about half of a coffee cup's worth over it.

Yeah I have yet to try the hot water, so keep me posted Chad if it actually works and doesn't come back. Joe Juice is fun to use to watch the Aptisia melt but comes right back. Uggg.

I have hundreds... some the size of a toonie! I even have some attached to the glass....

Update, the hot water worked 100%. The only downside to it is it also killed the red coraline algae that was on the infected areas. The very edge of a blasomusa polyp was damaged by the high temp but it looks like it's recovering nicely...
Take that aptaisia!

I use an even more brutal approach. I take the affected rock out of the tank and dip the affected area into boiling water. Yes part of the rock is killed, but so is the Aiptasia. In time the rock recovers. I have used the same approach on rogue Button Polyps, and that plaguelike red macroalgae.:evil:
