Sorry, Def. I was referring to the ram, not the CPD. I have 5 CPDs (ordered 12 from an online shop a couple hours from home, paid a ton for shipping, 4 DOA and 3 that didn't make it much longer than arrival, and I have 0 response to email, phone call, and text messaging since 4oct18, so won't be using them ever again) but will hopefully be picking some more up locally. Found a place that has them as of today, so I hope they're still there when I go to make the trip tomorrow. They've just started venturing out from the shelter of moss, wood, and hygros this week for more than just food, so they're getting comfortable.
And yes, I seem to recall that glass cats are schooling fish. Then again, I was told that at one of the common pet stores, so YMMV.
