WHAT in the WORLD?! ID THIS!!!

also it may be a stomatella snail.if its a stomatella snail its good.i could'nt see it well enough

 

Its def not a stometella snail. IMO it is an sphaeromatid isopod.....harmless once again.

 

Great post! I have been lucky enough to have never had to deal with parasitic isopods.

 

Thanks for the info. Like Amcarrig said I'd rather be safe than sorry. I looked up several kinds and mine had the markings of a parasitic one (or one that was labeled as a nuisance rather).
I'm going to keep seahorses so I'm trying to make the safest environment as possible for them.
The pics weren't too clear to get a proper ID, sorry for that. But I figured if I didn't know what kind it was Id rather flush it now than wait until I get my ponies to worry about it.

 

I understand your idea of not risking it. If I were to start a species tank or something similar to a seahorse tank, I would make sure all rock is dry rock, all sand is dead and all macroalgae get freshwater dipped so it is more of a controlled environment. All of my rock, sand and macro comes from a system that is 10+ years old, so the diversity in my tank is kind of scary.

 

some of the rock in my systems came from the ocean.

 

i have no idea what it is but i think have had hundreds of the same bugs for a long time, i know mine came from the beach sand i added early on, i've never seen em harm anything and my fish wont eat them either, they shed their skin like shrimp do and have sustained themselves population wise. i wouldnt worry about em
