What do you guys think? I have 3 red leg hermits now, and theyre happy as can be. What kinds of shrimp would look good in there? I dont really want fish bc of the bioload. Also what about snails & starfish? I think in a week or so I'm going to try my first hammer or xenia. What do you have or reccomend me getting? I do 1/2 gallon water changes weekly FYI.
