what type of snail?

[aggrofish]

Sorry for the crap photo but it's about as good as I can get. I have a lot of these things all over the glass and the one at the top is the biggest. I have a variety of snails and something must have had babies. Tiny/white/appears to have a shell on the bigger one. They're all over the glass. Thanks

Can’t really tell, but look into collonista snails they seem to be a pretty common hitchhiker.

hmmm If it's that it must be a hitchhiker cause I never added that. I do know I added astraea, ceriths, nerite, trochus, nassarius, and marginella.

Yeah, but they don’t look like any of those. They look like collonista snails. If they are, it’s not too bad, but they multiply quickly, and I could imagine them out competing some other species of snails given enough time.

I have always had them (Collonista) hitchhike on live rock.
Also, have you ever seen any aggression from the Marginella snails? I have heard that they might consume other, healthy snails.

+1 on collanista

I honestly never see them. Whenever I feed I have an army of hermits scouring the sand bed and the nassarius pop up from the sand...maybe the hermits killed them or they got suffocated by green hair algae lol

well if its collanista I'll start just picking them off the glass like I do with asterinas

You can but they do breed readily and due to their small size will hide in nooks ad crevices

I’m guessing they’ll eventually self regulate their population based on available food?

Yes- take away their food source and they come looking for some or starve out

I pulled one out to get a better pic. Looks like trochus to me
