Drastic measures for eradicating aiptasia

[mark]

The hit and miss with Peppermint Shrimp and aiptasia seems can be partly attributed to mis-identification.

The true Peppermint L. wurdemanni (which eats aiptasia) is quite similar in looks to L. rathbunae (which doesn't always develop a taste).

Though I've allowed (by neglect) the aiptasia to come back, I managed them before by the ones I could reach with Kalk paste (made with mysis juice) and with Peppermint shrimp the ones I couldn't. For some reason shrimp (Peppermint or Cleaners) don't seem to last in my tank more than a couple of month.

Here's one article on the two species.
