Black hitchhiker id help

[Nfd552]

Went to look at my tank after the lights had been off for about 3 hours and noticed this black critter just over 1/4" long on my rockscape. Slides across the rock space like a snail, doesn't swim or crawl, to hide when I turned the lights on so I apologize for the poor quality photos. It appears it Has two antennas, and is all black. TIA

probably a stomatella; they can come in different colors, but I've only had tan colored ones take a stroll when the lights go out

My best guess would be stomatella as well

Thanks. That's what I was leaning toward. If I can get a better pic I will

Safe to have?

Very cool, I've never seen a black stomatella before. They are great to have!
