I'm downsizing from a 75g to a Fluval Evo 13.5g within the next couple of weeks. Sad to see it go but I have a new job and I'm just way too busy for the bigger aquarium so I need something that I will be able to manage better with my work schedule. Fortunately I didn't have many fish in my 75g to begin with, it currently has 1 royal gramma, 2 clownfish, and 1 pygmy hawkfish. I'm wondering how many of these fish I will be able to keep happy in the smaller tank and which I will need to rehome? I'd love to keep them all if possible but I don't want to overcrowd it. I will also be moving over some of the snails and 1 emerald crab in addition to a few of the smaller corals. Any advice would be much appreciated!
