I have a 20 gal. tank. It has a 20-30 gal pump, a current fan (not using), thermometer ( reads between 78-80), 20lbs of live rock, cleaner shrimp, scooter blenny, 2 banggai cardinals, 1 pajama cardinal, turbo snail, small green galaxy coral and a pulsing pom pom xenia. We use R.O. water. I feed the fish mysis, they go crazy over it.
The 2 clowns get along. I have no idea if they are male or female. Nemo is slightly smaller though. I would put pics up but for some reason they won't upload. They have done that weird dancing thing at first but it only happens once in a while now.
I was thinking on getting them an anemone, but they can be a bit pricey. The tank they came from didn't have one.
