Are these snails?

[Dustin B]

These are in my 13.5 in the chambers on my heater. What are they?

What is that!! A R2R guide to common new tank hitchhikers.

One of the greatest things about starting a reef tank is getting your live rock in and admiring all the diversity within it. The rock comes to life different creatures. This is a guide that I, along with a very well known critter identifier @KJ , have put together for the new reefer on what...

Well that's good, didn't want to hear flatworms.

Do they spread quickly? My tank is only 5 months old and there are probably 15 that I can see in the small 3rd chamber.

My tank right about 1 year mark and in my sump I got maybe 100 lol.they like dark or shaded areas and usually explode in numbers in alot of never tanks then settle down and go less in numbers .
I can see a few here and there in dt and probably many more in and under the rocks that I can't see.
They huat filter feeders so I don't worry about them tbh.

Pineapples are short lived and thrive off of silicates. If youve added new rock or sand or have RODI filters that are expired or used up- these will emerge and prefer shaded areas of tank

All rock and sand has been in since the beginning (5 months). I get water from lfs. Should I be worried about silicates? How would I test for those?

In my experience, a 5 month old tank with pineapple sponges isn't anything to worry about. While silicates may be from another source, I would suspect your current rock is new enough to be the cause.
