Imagine this. Your Local fish store finally has the fish you want to add to your tank. You buy that fish and eagerly rush home to put it into your tank. Come to find out, the fish is not what you expected. Maybe it is too aggressive for your tank, or maybe you just did not like how it interacted with the rest of your tank inhabitants. I am wondering, have you ever had livestock that you regretted getting or simply just did not work for you. Photo Credit: @mk_reefs
