I had the opportunity today to get some more ghost shrimp from PetSmart(the only place that sells them around here) to add to my tank so my male won't be lonely anymore. I noticed as I was acclimating them that one male had red wristbands and some red antennae. My roommate said his arms looked kind of long compared to the other male that was in the container with him.
Other than this, he looks like a male ghost shrimp. Does the red markings mean he is a macrobrachium? I kept him separate just in case.
Xenxes- That's what he looks like, except no green spotting and he's missing an eye. They're in a ghost shrimp only, 5 gallon tank. I don't want them eating each other, that's what I was worried about.
Ghost shrimp shouldn't eat each other, but they definitely will eat other species when they get large enough. My large male ghost has the same red antennae/red band that yours has, and gave it to some of his offspring.
When I was transporting them home, I think the female got very hungry. Cause they were intact when I got them. When I went to acclimate them, the red banded one had an eye missing and the clear male had part of a leg missing.
