This is a pic of one of the new vampire shrimp. If anyone happens to know a genus on these, it'd be nice to know as searching vampire shrimp is an absolute shitstorm on google.
I think this new gang of shrimp understands that it's imperative to leave whitey alone. They may have better weapons in the form of pinchers, but newts are far larger and would beat the hell out of them one on one. I haven't seen anything beyond the one smaller one losing a portion of arm; that said, if I am late on a feeding by a day or something I suspect one will get chewed on.
So, the little ecosystem is growing, but the drama is cooling down a bit. Though Sigourney is stepping things up and has been seen in open combat with both Bowagrius and the larger female, biting back when bitten and etc. Looks like she wants some territory. I am kind of biased towards her, so I'm cheering for her to kick someones ass and claim her place as a popular newt.
