I have a violet goby, some blue legged hermit crabs, and a huge Thinstripe hermit crab in a 45 gallon tank. I would like to upgrade them to a 100 gallon tank because I feel it’s more humane for the goby long term. I want to restrict it to fish from the area where these animals are from (western Atlantic). Can anyone think of a brackish fish from there that will get along with the current stock?
