Can turbo snails breed in captivity? Is that what I'm seeing here?

[hhaase]

I had some tiny snails show up in the tank tonight that I hadn't seen previously. I hadn't seen any snails breeding in here previously, and the turbo's are the only addition to the tank in the past year or so as far as snails go (that I know of anyway). They are definitely more rounded in shape, not a cone, but I'm mostly concerned that I didn't accidentally bring in some pyramids, as I really don't want to lose my derasa that I just put in a week and a half ago.

Here's a couple pictures. Best I could do without breaking out the old manual focus macro, these things are maybe 1mm-2mm in size. They are on pretty much every surface of the tank in low quantities, including the glass and rock, the photo on the clam is mainly because it's the only photo I could get of the shell-side of the snails. Looks like I also had an asternia on the clam at the same time. I've had those for a long time and they don't seem to bother anything.

Look like collonista snails, common typically described as harmless hitchhikers. They multiply stupid quick so seeing them everywhere checks out until their numbers drop over time.

Snails spawning in general isn't unheard of, but more likely they are hitchhikers. Turbos don't typically survive the water filtration when they hatch. Couldn't tell you why the hitch hiking ones have an easier time swarming tanks like ants compared to the ones we buy.

Pyramids are very pointed with an opening at the end, you can see a comparison from this thread: https://www.reef2reef.com/threads/pyramid-snail-removal-tips.57886 you're safe there but an inspection wouldn't hurt.

from what I can see , One is an asterina starfish which not welcomed in my tanks and multiply like mice and what looks like a critter called an astrocod which also referred to as grass shrimp which feed off various algaes (film, surface, etc)
Turbo snails lay eggs. The male will will wait for female to lay eggs and then the male transfers sperm to female via her mouth and the female stores the sperm for her egg release. I know- Yuk
Collanista also possible but microscope image looks like ostracod

The asternia's have been in the tank for quite some time, and I know their reputation, but in mine they haven't been an issue. So I haven't done anything to chase them down. Didn't want to exchange one issue for another by trying to kill them off.

Looking up the Collanista, it does match what I can see with my eyeballs. I'll try and catch some photos tomorrow when the lights are on and I can get a better image with the macro. They're definitely snail-looking, not like an amphipod. Given my algae issues lately, the Collanista's wouldn't necessarily be a bad thing right now.

Definitely nothing at all like the photos you linked of pyramids, so I'm going to just monitor these things for now.

They are harmful. Jam up pumps cause major problems.
