My friend bought one after seeing how attached I am to mine. His is active as HELL; lives with a bunch of cichlids; and happily competes for frozen bloodworms with his tankmates.
Actually, it was really cool: One night last week I went over there with my better half for dinner and drinks. He keeps his doors open when it's nice, and I noticed a large green grasshopper in his kitchen (where he keeps his tank). I told him how much my Aro used to like crickets, and he decided to throw the grasshopper in (not something I would do to with my own tanks for fear of pesticides, but hey, we'd had a few). It was awesome, the first REAL strike actually came from his 3" sen. bichir. After that, all of his young cichlids joined in and the thing was destroyed.... Sorry, I seem to have gone on a bit of a tangent. I just really like these fish.
