right after i cleaned all my glass tanks out, i found several berried marmokrebs, so one went in each tank, then i found a couple clay pots covered with eggs..i was reading about fh/rr minnows and the study showed that the males preferred to go in and take over an existing bunch of eggs, and that they'll breed many times in the same spot, up to several males for one "brood".. so i got luck and caught everything at the right time, got a male and two pots, he took care of both sets of eggs
