Ok so today i picked up 4 little ghost shrimps. (had i known the rule about 10 per gallon i might have picked up more, their fun.) one is pregnant. it has eggs in the abdomen that are green and black. What can i do to raise some fry? should i go out and buy a little breeding tank tomorrow? can i use a betta cup and tie it to the outside of my tank and just scoop the female up in there, till she lays or spawns? then remove her and leave the little ones in there? any tips? im super curious and would love teeny little ones!
