I have a 16g with LR
, hammer corals, zoas, a small pair of ocellaris clowns, an azure damsel, a diamond watchman goby and some various hermits, snails and shrimps as a CUC. I like the fish you've chosen. Gobies are great, and I like the yellow one as well as the one I got. There are a few really good looking gobies to choose from. I also really like green chromis, if you want some more color in your tank. Just be sure to take the time to add them properly, not all at once, so your bio filtration can catch up. Good luck. Your tank will be awesome!
