I recently moved and upgrades the 20 gal to a 40 gal. My gramma didn't make the move but my clownfish are thriving. My coral growth is slow, but growing. I've found anything that's orange just doesn't survive in my tank for some reason. My duncan and leather corals are doing the best and thriving well.
I started a 10 gallon to be a snail quarantine, and a tank just for rock flowers and sexy shrimp. I really love this simple tank. I think rock flowers are my favorite type of reef animal now. I'm trying to build a green star wall. I think I will do the same in the 40 gallon. The 10gal also moved with me and had been running for about 9 months.
