40b

I just set up a new 40b over the weekend. Everything is new, tank, canister, glass canopy, cichlid substrate, ect. Only thing I bought used were little caves I found in a dry goods box at LFS for cheap. Also bought 2 live plants. Tanks running 3 days and I see these tiny little things growing on...

Can I put a juvenile salvini & juvenile Jack Dempsey in a 40 Breeder til I get a bigger tank & if so how long?
