Woo those are bright!!
They really are! The rest of my cherry shrimp are fun to watch, but every now and then one of these PFRs will crawl through the plants near the front, or swim across the middle of the tank, and it is absolutely eyecatching. The other shrimp become much less noticeable in the presence of the PFR.
I'm debating whether or not to set up a PFR-only aquarium. I do want to improve the color of my colony in my main tank, but it sure would be cheaper if I had a breeding colony of PFR that I could use to add color to my main colony, instead of buying a dozen here and a dozen there.
