Garage update. I decided to have more fun in the garage. I drilled a 2nd tank. This is only 10 gallons on the left, 20 gallons on the right. I plumbed them both into a 20 gallon fiji cube kit sump. The plumbing was a PITA. Working well now. Temperature is the main issue. It's in the 50s in the winter and 90s in the summer out there. So far lots of fans and lots of heaters are working. The 10 gallon is still going through the ugly stage. I am using the 10 gallon as a quarantine tank. Any new fish go in there for 2 months before the house tank. Not sure about the green chromis though. I feel the house tank may be pretty full of fish for now. We'll see.
