I am currently a rookie in the fish keeper game and am looking to get some info on some possible fish that I could keep. Originally I was thinking about going with the prantis shrimp but decided that they are too boring becuase they stay hidden a majority of the time. So I have decided to go with fish as they are much more active. I currently have a 10 gallon setup and will eventually move to a larger 200+gallon but I want to get this fish keeping thing down before I take on something big like that. I was thinking about 3-4 dwarf puffers for the 10 gallon. My question is what other mini monsters like these would I be able to keep in the 10 gallon? I know barracudas are out cuz none are that small and same with Piranha...appreciate the help guys.
