Beautiful. I love it. I'm trying to do the exact same thing with CPD fry and shrimp in a 2 gallon. A few question if you don't mind:
What age are you putting the CPD fry in there? I'm worried if I breed the CPDs in there, the shrimp will eat the eggs or harm the newborn fry?
What are you feeding the CPD fry? They seem so tiny to me.
What age do you transfer the fry out into the adult CPD tank? How long can they live in a 2G? When are they safe to add back in with adults?
How many fry can you have in a 2G? I bred my CPDs in there and now I have like 40 tiny fry. I'm not sure how long they can last in there together as they grow?
Thanks!
