now that's what i'm talking about! nice pick ups!
one bit of advice though - i would be very careful about that large pleco... they have a taste for discus slime. also i think those are somewhat more carnivorous too. not that i am suggesting it would go after your discus, but that's something you should be careful about.
in addition, i personally think the rays, while cool may not be the best tankmates. discus actually like to poke around and feed on the tank sand area. having so much activity down there really limits their behavior.
in any case, nice pick ups - i really like wild greens. good luck with them!
