Do NOT buy nudibranchs! Why? This post will tell you just that.

First up, what is a nudibranch?
Nudibranchs are vibrant gastropod sea slugs. Their name comes from the Latin "nudus" (Nude) and Greek "brankhia" (Gills).

So why shouldn't I buy them?
Because most of them feed on sponges that you will not find in the aquarium trade. Anybody that tells you that they feed on algae is trying to trick you or they have no idea what they are talking about. And some of them have toxins, too.

But I want them real bad!
I know, I know, their colors are amazing. But you're better off getting the real algae eaters, sea hares and the lettuce "nudibranch". Or you can get sea cucumbers, their colors can be striking, too.

I want a real nudibranch!
If you have an aiptasia invasion, you're in luck. You can get berghia nudibranchs, they will eat up the aiptasia.

But berghias don't have the cool gills!
If you really want to, you can buy one. But they will only live for 1 or 2 months.

I don't believe you!
Well then I challenge you to keep a "true" nudibranch alive in your tank for at least 4 months.

I believe if you are "blessed" with a flatworm outbreak, a blue velvet nudibranch may be an option.

It's not a "true" nudibranch though
