Thank you everyone... After having Hans' fish for 10-12 months and trial/error with that tank & equipment, I knew exactly what I wanted to do with the 90 gallon. I took my time setting it up, making sure it was perfect and ready (and of course fully cycled from scratch). It's bare bottom, running an FX6 with a spraybar, sponge filter, air stone, 4 large faux bamboo plants, black background, 2 AI Prime Reef lights, dual 200watt titanium heaters with an inkbird temp controller. I'm very happy with this setup and the fish really are so healthy and lovely to watch.
