Amphipod population and the mandarin dragonette

That is a cool vid but I don't think that would work with my stock or other tanks stock. My fish would devour it long before the mandarins got a shot at it. Mandarin on mandarin competition is much different than what's in the majority of everybodys tanks I assume. I think your tanks pod reproduction capabilities would be the key everytime. I am a newbie so just throwing this out there. I have a corner of my tank piled up with 1/4" to 3/4" crushed coral about 3-4 inches high in hopes of an additional place in the dt to reproduce pods. My green spot is always hanging out there plucking away. I do have a fuge were I can spot em anytime I want and I know they make their way into dt from there. I like the thread tho as I have to mandarins and a goldenhead sleeper that makes his dent on the pods too. So I'm always looking for ideas on mass reproduction.(Without a second tank devoted to it)
