I agree with Dx on this... give the angels something to hang aroun/spawn on off the ground. the only problem i could see is if the angels spawn near the bottom and bite the ray to keep him out of there territory.That shouldn't be a problem... You could put some driftwood suspended from the tank bracing for the angels to congregate around, leaving the bottom open. Here's a pic of my tank when I first set it up. I have some fake plants now, but still plenty of room for 2 rays to get around.

If you go with the wood, you could attach some anubias or java fern to it.. if you want go platic plants zoo med makes a line of "reptile" plants that come with suction cups. I use them in my panda uaru tank because they eat everything else.Hmmm... your giving me an idea... I wonder if I can somehow dangle some plastic plants from the brace and make it look good? I'll have to experiment with that. If not, I like the wood look as well though! Thanks for those pics! That is a great idea!

HA HA! Had my "epiphany" same time as you were suggesting it! LOL... and maybe I'll use both! Be nice to maybe drape some of that plastic hanging plant on the back glass... I'm liking how I'm picturing this in my mind, anyway!
