I have a 3.2 gallon (7x8x9) and want to stock it. It currently has a some zoas, montis, hystrix, chalice, candy canes, blastos, and leathers and a single hermit crab. The tank has a lot of vertical space. I’m not sure what direction in terms of stocking I should go. I am wary of pistol shrimps due to their burrowing and potential to kill my hermit. Also it would be great if the inhabitants were relatively cheap. Any suggestions?
