ahh ^^; sorry for seeming confusing, i'll try and explain it better!
supplies
1: lock bin - it's pretty much a normal sterlite-type tub you'd use for storage, the only difference is instead of coming off the top is 'hinged' on and divided in two, when closed properly the two parts of the top lock together.
2: small desk lamps
1: box of saran wrap
1: 25w submersible heater
2: small sponge filters
1: air pump
1: roll of aquarium tubing
2: airline connectors - one to divide the two, the other to cut airflow down so both can have equal flow and one filter isn't excessively aerated.
5: bushy silk plants
1: styrofoam cup
1: power bar or three-way extension cord
1: livebearer breeding trap
procedure
1: put the bin somewhere unobtrusive, preferably near an outlet to plug in the air pump, lamps and heater. close the back half of the lid.
2: stick the heater and filters onto the tub, hooking up the filters with the airline tubing. cut two long pieces of tubing, and two short pieces. take short piece #1 and attach it to the pump, then the other end of it to the first dividing connector. then the second piece of tubing goes between the divider and the second connector, which should have a small screw-valve to cut down air flow. hook the third piece of tubing up to the second divider and into one filter, then the second long piece from the divider to the second filter. rest the air pump on the lid.
3: add water.
4: tie the silk plants together with a twist tie, wire, a cable tie, anything that will hold well. put the bunch in one corner, preferably away from the filters and on the far side of the tank. on the other side, put half of the styrofoam cup and anchor it down however you need to, if at all.
5: put the lamps on the part of the lid that is closed. cover the other half of the top with saran wrap, and poke holes through the saran wrap so oxygen can pass through.
6: plug in the heater, air pump, and both lamps.
7: introduce the pair. first, the male, add him directly to the tank and let him get a feel for it. then, the female, in the breeding trap. leave her there for about 24 hours, so they get a chance to know the other is there, then release her. watch for 48 hours, if they do not spawn or attempt to spawn, remove the female.
this is not a 'tried and true' method, it's just something a soon-to-be-backyard-breeder thought up in her spare (-cough- school) time!
