CBG's first SW tank - Fluval Edge 6G now with 10G sump

[CGY_Betta_Guy]

So now I am at the point where I am starting to think of stocking my 2-3 small fishies... will be picking up a red fire shrimp along with some more snails this evening I think. I would love to find a red mandarin goby that eats anything and wouldnt mind the small quarters but I hear there are quite some challenges with this fish though.

Any other fish suggestions out there?
