I have a 29 gallon aquarium only a few months started... I want a clownfish well a pair in my tank...I have heard keeping anemones is quite difficult for a novice is there any other substitutes a clown will host that would be just as good as an anemone... I'm only gunna have clownfish, maybe a goby and pistol shrimp and I currently have 2 hermits and a nassarius snail in there... I want to have predominantly coral in there so any other advice would also be greatly appreciated
