Hello all!, I have a 14 gallon tank and its currently stocked with 1 yellowtail damsel and 6 dwarf blue leg hermit crabs. The tank has been running for close to two months maybe a couple days short. I was thinking of tankmates but could not come with much given the small size of tanks and that damsels can get pretty aggressive. Anyone has any ideas for a tankmate?. It has to be reef and invert safe. Thanks!
