Tiny bivalve

[Sarah155]

I noticed this a couple of weeks ago but it wasn't close enough to the glass to photograph. I assume it came in on my macroalgae from gulf coast Ecosystems

. It looks like a small white bivalve with a really long foot. It climbs with the foot. Any idea what it is.

Pic very fuzzy, but appears to be a baby nassarius snail

Yeah it is really hard to see/photograph. I attached a video, it does look like a clam of some sort in person. Hopefully it will get bigger and be more easy to id.

It even meows (ok- I had to)
It is indeed a bivalve which is a member of the scallop grouping as uses appendages to cling and move. Its a harmless filter feeder and generally Not long lived although mine's been around a couple of years. They seem to come into a tank when zoas are introduced

Yeah, it does seem to be a bivalve - hard to say what kind with how small it is though. I hope it does well for you! If you want to try and help it grow, then you can try offering it some Isochrysis galbana (T-Iso), Chaetoceros sp., and/or Thalassiosira sp. if you can keep track of it, as many bivalves are known to feed (and spawn) on these.
