I put my clutches IN a tupperware, that has half water from the parents tank, Then I take a pc of stryofoam and lay the clutches ON top of the stryofoam pc, and Float in the tupperware dish , I put holes in the top, just a few cuts X ~ Then I place the tupperware *(hatchery) on top of my strip light fixture . I get clutches to hatch FAST this way ! Then You could put your babies IN thier own tank, even if you dont have a xtra tank, you can use a sterlite container I have one thats 6 gallons. I put a sponge filter in , a heater And WALA ~ fresh strong baby briggs !! And YOU make them strong by putting calcium in thier tank . Just buy a bottle of the calcium pills vitamins, yes, like you would take, I split one in half , and put one half on each side of my tank (sterlite container) Then they will eat the calcium, and also this helps them grow strong healthy shells, so they dont crack, or break ... Its best for them
~~ You can then sell or give away the ones you dont want . And keep the ones you do . I think its fine to have them in yoru community tank as long as thier not getting picked on, and with your crew of fish ~~ WOW ~~ I am surprized they laid !! They must NOT be being bothered which is GREAT !! My angels & gourami & mollys would never leave my briggs alone !! I had to always take them back out the tank . Anyway , even the adult briggs can get a calcium bath" , You can just put them in the calcium enriched tank with babies for a few days, then put them back in yrou tank to enjoy
~ This is what I do . HTH ~~ and Good Luck ~
