Ah, yeah. They're fun though
When I first bought them I had no idea that they were filter shrimp or what they did, I just wanted one or two. Came home to find out that I needed to make a better spraybar for a stronger current and feed them individually.
I just use a turkey baster though and it's so simple, I put some near both bamboo shrimp and then some by the frogs, it was more so making a good current along with places for them to be up in the current that was a hassle lol.
And like you could see in the video he must have been catching some type of debris because he'd eat whatever was on that fanned-leg, then eat off the next. I have no idea what the spaz-out was for though LOL weird shrimps.
