Pest

Thursday as I was doing a quick water change I found a tentacled creature sitting on top of my first sump baffle glass.... looked like an aiptasia to me so I tried to suck it with the hose. It receded into the baffle and I lost it.

A few minutes later I saw it drifting submersed in the water on the other side of the baffles, close to the return pumps, stout and tentacles all spread open, like a spider. This time I took it out with plastic claws (didn't want to touch it).

On June 4th at night I added two peppermint shrimp to the tank, and they gradually ate up all the Aiptasias. And there were a lot... but they got rid of them, all of them.

Well, to be honest they ate all but one, the large, no, huge, Aiptasia you saw in a previous blog post. So I decided to manually remove than one and put it in a flower vase for my amusement. This picture was after a week it was in the vase, it climbed up from the bottom to that position:

In January I spotted one Aiptasia in the display tank, then shortly after another one. Bought some Aiptasia-X a few weeks later and killed them both.

Well, two months later (March) I spotted them again... a large one on the substrate, and 3 smaller ones on the rock. The large one and one of the smaller ones were almost exactly where the two ones I killed in January were.... humm.... I re-read Aiptasia-X's instructions, applied it on them again, and gone they were (the four of them). ...
