Lettuce sea slug macro safe?

Are lettuce sea slugs macro safe? Scientific Name: Elysia crispata

I've had them on several occasions in the past and never had them eat any macros.

Thanks. I just added one to the tank. He found the hair algae right away.

They prefer Penicillus (shaving brush), and Bryopsis, but will eat Halimeda and Derbesia (green hair algae) if pressed. They won't touch any red or brown macros.

Is it crispata or clarki? If you bought it online, it is almost certainly clarki. Below is a photo from Sidney Pierce's lab, showing crispata on the left.

I have collected some info on the genus in a web page, solar sea slug blog

I had one and loved it. It was by far my most active algae grazer I've owned. I had it for several months and it never touched my macros, only hair and turf algae.

Unfortunately it went after the algae on my power head and got minced into fresh fish food.

Thanks for the web page Morgurnda, and the info too. Fellow slug lover here.

Glad to know there are more of us out there. :wavehand:

Best hair algae eater I've ever owned. Have trochus snails, cerithia, sea cucumbers and tangs and turbos but gram for gram none can touch the lettuce sea slugs. Just ordered five from LA for a 180
