Keeping a viable pod population in a sump?

As I review my prospects of future employment in a distant town (I may be moving to DC), I am faced with an unpleasant decision: my 110 gallon tank is going to have to be shut down. I won't be able to keep it in the place I'm moving to, and the family members who are staying behind for a few months just don't have the time and resources to keep it running anyway. The silver lining in all this is I can take my 37 gallon tank with its seahorse tenant, and I have chosen a couple fish from the Big Tank who can live peacefully in the seahorse tank. Naturally, my big peach toadstool is making the transition, as is a McCoscker's flasher wrasse and a small selection of nassarius and fighting conch snails.
A much harder decision to make will be what to do with my two green mandarins in the big tank. I have a male and a female who have spawned together a few times in the past. I would like to keep the female, but I haven't decided fully yet. My wife is pushing to keep the much larger male, who does eat frozen mysis from time to time.
And there's my dilemma. Do I take the smaller female, who doesn't eat frozen but obviously doesn't eat as much food since she's.....petite
..... or do I take the big boy who may decimate a pod population faster but eats frozen if he has to? The reason it's such a hard decision for me is because female green mandarins are kind of hard to find anymore. People clamor for the males with their display behavior and their spikes, so I can always find another big male when I set up the big tank in a couple years. Females are simply hard to find.
My 37 gallon tank has about 40 lbs of porous live tufa rock, macro algae growing in the tank itself, and a trickle sump that has glass rings in the bottom of the pump area. The walls of this tank are constantly crawling with pods, and the last time I cleaned the bottom of the sump I discovered a huge population of amphipods and certainly copepods feeding on the detritus down there. Pods don't really need the light from a common 'fuge, so I started wondering - is it possible to keep a mandarin-sized menu of pods breeding in a common sump filter? Does anyone have any experience with this?

I think you answere your own qestion, keep the female. She will be able to live off your pod's and you dont have to buy foren food for her. Making your decision easier is just how hard it would be for you to find another female. So, let em know hat you chose I would like to hear more. Good luck
P.S. Do you have any live rock you are looking to get rid of from the large tank?

What I'm really curious about is hearing from people who have sumps (not refugiums per se) and who have seen pod populations blooming in a plain sump style filter. I agree with you; I'd prefer to keep the female, but only if she has an acceptable pod population coming from the sump.

I do have a running sump, it is not a filter, I have my fluval 405 for that. I will soon be working on setting up my sump to propigate pods. I will probably put another pump to bring them into my tank. So best of luck with yours.
