I am not one of the many shrimp experts here but I heard that a shrimp tank typically needs a thick layer of substrate. Does 45F sound to shallow?
Not really, as many professional breeders as well as hobbyists sometime use bare-bottom tanks. On the contrary, the shallowness and wide surface area of the 45-F allow for plenty of space for shrimp to spread out and more surface area for gas exchange, making it a good choice for a shrimp tank. shallow tanks, in general, are regarded generally as good tanks for keeping shrimp.
Jake, I can't wait to see this! I think that the orange bodies of the Pumpkins will work well in contrast with the orange eyes of the BTOE, and vice versa with the black eyes of the Pumpkins.
