HELP my jewels are like rabbits

hi guys just need a little advise ....i have a breading pair of jewel cichlids and the little *******s are worce than rabbits....they will lay the eggs and less than two weeks later shes's laying eggs again and then 2 weeks later again its crazy i have fry coming out of my fry i cant seperate them coz i only have one tank and i cant get another tank coz no room in my place ......so do you guys know a way to get them to spawn less often ....is it the PH or temp that triggers them ...HELP ...the other fish have a snack on the fry but there is way tooo many ....the jewels are like machines ......i've never seen anything like it ...i've kept alot of cichlids and this is the first time something like this has happened ...my other pairs will spawn maybe once every few months these guys are going hell for leather its like they are newlly weds ....HELLLLPPPP.....

That is strange so your putting two days into one for them....does it matter that there is light in the room from out side....my lights are set up to go on at 2pm and off at 11pm...i guess i figured thats when people are home so you can see the little rabbits...but when its day light out side there is still alot of light coming through the window during the day even with the curtains closed....or are they acting specifically to the aquarium light not the out side ambient light.....???

I did that with the first few batch's but they wont take them unless they are at least 1.5" to 2" inches so it take a little while before they get that big and plus the local FS cant sell them quick enough for me to keep bringing the little buggers in...what i need to do is plug up the female .....does anyone know of a contraseptive for chichlids......
