I'm thinking about getting this tank for a single CPO. No shrimp and probably no snails. Not sure if it would have any fish added. How is your CPO with the Least Killifish? I know that CPOs can kill shrimp, snails, and fish so I'm hesitant on adding any tank mates. Also the light you have, do you think it will grow low light stem plants?
I'm sorry about your TT shrimp. From what I read, Tigers seem to be picky.
