Please Help Me ID

I noticed a couple weeks ago that these started showing up in my fuge. Anyone know what they are, and if they are good or not. It looks like some sort of slug and just seems to be eating the Algae. I haven't seen any in the main tank yet.

I have at least 15 or 20 that I have counted so far.


Thanks

look up flat worms.not all are bad but most

 

Very cool, I don't think I've ever seen those before. They don't look like flatworms to me. I'd bet they are opisthobranchs, although I don't know where to start looking for them for sure. I'm headed to work, but suggest you try

The Sea Slug Forum - Species List

and look through the Cephalaspidea first and if you don't find it, try the Sacoglossa.

OK, I had a chance to search a little on my break at work, and I might have found your little animals. It's kind of hard to visualize your creatures in three dimensions, but I think they are Bubble Shells, in the order Cephalaspidea as I guessed. There are several different species that look similar to yours, but the most likely one is probably a species that's native to Florida and the Caribbean, Haminoea antillarum. If it's that species, it should have a thin vestigial shell underneath the mantle, even though you may not be able to see it. Check out this link and see if you agree:

If you want to compare to some of the other species in the Haminoeidae, scroll down to that family under the previous link I posted. Some of the others that look similar to yours are temperate rather than tropical, so keep that in mind while you're checking them out.

Dr. Rudman says all species of Haminoea are herbivorous, so if your animals do indeed belong in that genus, they should be nice little tank residents.

Thank you so much Pagojoe, that is exactly what it looks like.

At least now I know that it is good to keep,

Thanks
