Review on Floating Breeding Trap - Triple Function Convenience by Roberto Cohen

I've had several of these and they've all worked well. Somehow my females don't give birth in this trap. The day I release them back into the tank, the babies will be born. Not sure if this is just a coincidence or maybe I have weird fish? In the last 3 months no babies have been born at the breeder and/or my bitches have died. Maybe it should be bigger? Very frustrating. For that reason alone I'm giving it 3 stars.
