How to kill/remove individual zoa polyp from a rockwork.

[cvu]

Hi any suggestion how to do it? Aiptasia X? Basically, I would like to redraw the boundaries of each zoa species to prevent the more aggressive ones taking over all the real estate. Or remove some polyp that randomly shows up in the middle of the other specie colony. TIA.

Kalk paste works, but don't do many polyps at a time. I've found all of my Euphyllia react when I start killing palys. They close up for multiple days.

Another idea is to take a large metal boba straw, fix it to ATO tubing or siphon tubing (may need to wrap the straw in rubber bands to make a seal), create a siphon into a discard bucket, glove up, then get into the tank with the metal straw and scrape the end of the straw against the palys, sucking up the bastards as they come off the rocks. Extra safety would be to have a lid on the bucket and feed the tubing through a hole in the lid to prevent paly juice spraying everywhere.

@JojosReef, I like the metal straw method to reshape boundaries. Not sure if I can use it to remove single polyp among the others.

Overkill for single polyps. I would kalk paste them.
