Thanks for the ID - I thought they were both Cynarina =D
Lighting - That's a good question that I'm not sure on. When I got my two Cynarina they were in a metal halide set-up w/6.67 watts/gallon. My set-up is also metal halides and has over 9 watts/gallon. The first Cynarina sits a little over half-way up on a rock and is seemingly great, and that's where it was situated before. The second Cynarina is on the ground, as that's where it was before I got it as well. Neither have been in my set-up for that long though, so I cannot really say if they like their placements long-term.
As far as flow is concerned, I read they don't care for too much flow, so neither is in any high flow spot.
Btw - how is it that these guys reproduce?
