Blue and red Nudibranch

[gjones]

I saw this today, is it good, or bad. It's the little (1/4th inch) blue thing, with antenas, and red tiped flaps on it's back.

 

 

He is one of 4 different types of unidentified nudibranchs in my tank, the other three are green, or a paleish white and green color.

Here's another of the 4 species.

Second one is not a true nudi, but a harmless algae-eating sea slug. I always forget the name.

 

The first looks like a true nudi (may or may not be), and thus will most likely be a meat-eater, doomed to die in the tank, and may well release toxins.

How pretty that first one is! www.seaslugforum.net lists all types of nudi's so you could probably get a positive ID there.

Thanks for the great link Angel, it's very interesting.

Yup, it's a great site but there's no real way to search; you just have to go to the giant species list and go down the line. Helps if you know about these guys, and it takes forever if you don't.

the first one has the coloration of a sea goddess but its not cause the sea goddess doesnt have frills...but looks really nice

the others i think are lettuce nudis

Ehh, no on both of those. Again, the second is a harmless NON-nudibranch species of sea slug that eats algae.
