Baby Clam? and snail ID

MusicTeach · Apr 14, 2018

Hi R2R!

Fairly new to this forum. I jumped in during a cherry coral live sale -which proved a wonderful decision.

I bought rock from Tampa Bay Saltwater, so I have all kinds of hitch-hikers. I'm fairly confident about what most of them are, with the tank being just a couple days over 6 months old at this point. But There are a couple that I could still use some help identifying. I have attached them below. The first one is a snail of some kind. The second looks like a flatworm... except it appears to have a harder carapace on it - so I'm thinking some type of snail? The last one looks like a baby clam trying to crawl up my glass. The middle one I have only seen during the night. The first one is a day-crawler, and the last one I just discovered this morning.

Any thoughts?

Thanks!

I apologize for the double picture post - I'll figure that out in my next post. Thanks for the understanding!

The first looks like a whelk...maybe. the second stomatella snail good guy and the third I have no clue...

Maybe this link can help id the first snail as good or bad. Get rid of it if you suspect a whelk: https://www.ecoventuresus.com/infographics-conch.htm

The second picture looks like a flatworm. I can't see a shell and Stomatella snails have a half shell. I have several Stomatella snails in my tank, and they look nothing like what is in your picture. Check out the following link to help with Stomatella id: https://www.ebay.com/itm/Stomatella...ter-Clean-up-crew-diatoms-cyano-/232403218893

Third pic: I'm not sure, but you can search here for some ideas: http://species-identification.org/i...d+slugs&selectie=56&hoofdgroepen_pad=,1,12,56

Hope this is helpful.

Edit first post thought that brittle star arm was an antenna . That is a chiton and he' a good guy.

The snail doesn't look very whelk-ish to me, but it's for sure a snail I've not seen before. @Jose Mayo may have, though.

Photo #2 is definitely a chiton - they're like a snail wearing plate-mail, and they're great to have around.

Photo #3 does look like a clam or other bivalve, using its foot to climb your glass. When it finds a happy place, it'll likely throw down some byssus threads and settle in for some serious filtering. This won't be a clam that survives on sunlight and zooxanthellae, though . . .

The snail is a Cerithium sp., Without doubt, perhaps Cerithium echinatum still juvenile, but to identify the species would require sharper photographs.

So it's a baby cerith? My cerith snails laid eggs shortly after being put in my tank. Maybe it's a survivor? I have the white one, from the picture above, and a black one of similar size and shape. Next time I see it, I'll try to get a better picture. Thanks guys!

Regarding the bivalve, I feed phytofeast and goniopower twice a week - so hopefully that will help! Also, tank is 6 months old.... and it probably came on the live rock (Tampa Bay Saltwater), so hopefully if it's lived this long, it can keep it up

And cool news about the Chiton! Do you think this is another one? Or is this something else?
