Nano is Cycling, but...

Amanos (Caridina japonicum), ghost shrimp (Palaemonetes spp.), and some Neocaridina spp. can tolerate cooler water.
 
PurpleSmurf, thanks for the tip. I was reading about that the other day and making a mental note to wrap the filter intake with a piece of sponge.

Veneer, thank you for the info on shrimp types. I never see any around here besides the Ghost shrimp. It will probably have to be mail order then.

Yeah, Johnny, alterations will be required.

Back to the heater.... I don't believe I've seen one small enough. Any brand/type recommendations?
