I've got a 20 long growing emergent at the moment, and have some pretty good ideas on how to stock it. I've been a fan of the rummynose, but i've read a fair amount about their sensitivity, and was hoping to get a consensus from this crowd. I'm on a well, and my water tends to come out on the neutral-hard side. Filtration is a rapids mini canister, with the option of an additional sponge filter. For stocking I'm thinking 8 rummynose, a pair of bolivian rams and 4 corys, probably false julii, but any other suggestions would be appreciated.
