Hi everyone, i have a waterbox 20 cube. I’m thinking of what fish i should put in. Its my first salt water aquarium. Currently i have the idea of stocking it with a purple firefish and a blue head fang blenny. Then when these two fish have established in the tank i would add a royal gramma so there is less chance of aggression. I would also put some cuc in the tank i was thinking 2 mexican turbo snails and 2 colorful reef safe hermit crabs. Would this work in this size tank or should i reconsider my options? If so what other options do you guys propose? Thank you in advance!
