I have a cave and some dw my ornate and del dont hide at all but they do hang out where there is cover sometimes.. if were me i would want the fish to feel somewhat secure try some mopani dw.
Nice ornates! How large are they?Caves can look nice. I have a couple of big driftwood hollow logs with anubias attached. My ornates like swimming through the logs and staying inside to relax.View attachment 1131504
My retro is out and about quite a few times. Now it's even sit and watch TV from aquarium as wellI'd say don't do a cave but definitely have some kind of cover. The way I placed the wood in my tank I kinda accidentally created a cave and now my bichirs spend more time hiding under that then being out in the open :\
Seriously I see my retro once in a blue moon...and its a pretty fish lol
