I have just purchased 5 ghost shrimp to go with my male betta in his new aquaponics tank. Supposedly, the shrimp will work along with the plant to keep the water nice and clean. I have been advised that there is a danger of the betta attacking or even eating the shrimp, but my guy is pretty passive. Is there anything else I need ttttop worry about before introducing them? Any danger of disease? Or of the shrimp attacking him?
