my tank is a 15 gallon and its almost cycled. there are currently 8 minnows in there and i will be adding some cories and hopefully a couple of rams. are bolivian rams a good idea for a starter in the fish hobby? i know they are "sensitive". also, can i add shrimp or snails before my tank is fully cycled or will they die. and also, can i have snails if i have artificial plants. please comment on any or all of the questions!
