ok here i know what your talking about, i always lose a few fry when i put my momma fihs in the net and iv got a method that makes a world of differance. first off ditch the net and buy a 5g tank, they fry need a growout tank anyway. then by some java moss, one quart is fine. fluff out the moss so it takes up 3 forths of the tank. ok now add the very prego mother fish. stuff her full of food, spoil the littel buggar. 3-4 times a day feed her tilll she can eat no more. this not only keeps her appitite at bay but it will also help greatly in the health of ur baby fish makeing them loads faster and les prone to early illness. after mama has her babys she will probably eat a few, but she will not be able to eat them all as she is alrdy quite full and the babys are trenched in deep with the java moss. be sure you do remove the female thogh and keep a close eye on her while she is in the tank, leaveing her in the tank after she is done haveing the fry will definately sort you a few fish. also make sure there is a spong filter and a heater to keep teh tank clean and warm. if u are really intent on keeping the babys alive this 50 dollar invesment should prove effective. as for your plants dieing, java moss is very hardy, reqires no light at all and doesn't even need fertilizer. but i do recoomend buying a fertilizer/conditioner combo or the tank as it will keep the plant heathly so that it will last longer, its also good to have some kind of rocky substrate in there as well, less than and inch of medium sized gravel is perfect, they fry will hide in there as well. good luck!
