Hi all. Got some "ghost shrimp" at my LFS today, and realized something was wrong after some of them harassed my betta. I then fell into the rabbit hole of what a ghost shrimp is and that it could actually not be a shrimp at all, but a prawn. Anyway, some of them have tried EATING my bettas fins, and obviously they're going to have to move. My question is, how do I tell the difference between the desirable "ghost shrimp" and the aggressive macrobrachium? Do I have some of both? I read sooo many posts about this, but I still cannot distinguish as some of them seem to look different.
