This first one is Harvaard Stoere's (of planetcatfish.com fame) hemiancistrus subviridis breeder tank. All real rocks and natural sand found by him. Quite amazing. Even went so far as to cut some of the rocks to fit flush against the back and sides of the glass. Just amazing.
If I remember correctly, he patterned it after the Rio Orinoco.
^^^Tropheus duboisi i believe. Amazing looking fish, they go through some serious pattern changes throughout their lives. Do require special diet though.
