My pleasure. I hope to get some better pictures tomorrow.
As it turns out, I see them much more often now that they're in a 65g than I did when they were in the nano. I understand the impulse to keep a small fish in a small tank, but these guys really cruise around. They move through the rock work, but they also like to hang out near a clump of chaeto and hunt pods. I have a big ball of chaeto in my display tank, and while it's not beautiful, it is a hotbed of activity. The alligator pipefish hunts over there, as does the mandarin.
I've given up on the notion of having a pristine tank (I have about 9 types of nuisance algae that never get out of hand but never completely go away), and instead have allowed for some biodiversity. Everyone seems happy.
