Nudibranchs

[GregW]

I'm looking for nudibranchs with gills along their entire back similar to this one. I'm trying to get rid of stinging hydroids and these seem to be the only thing that eats them. If you see any for sale, especially in Monmouth or Ocean counties, please let me know.

Like this kind:

Not this kind with a small group of gills:

they are some cool looking critters.

It should be pointed out that many species of nudibranchs have very specific dietary requirements. I'm not 100% sure, but I believe only a few species will eat stinging hydroids. Be very careful in your selection.

In general I'd say look for another way to control your problem.

Also to note that when they are stressed, the will release toxins in the water that will kill everything in your tank. I would use this as a very last resort.
