about 5 days ago i got some guppies for my 55g tank and one of the females was pregnant. thismourning she looked thinner but i had to go to school. today when i got home i relized there was fry in the tank! i was only able to find and save 4 i think the others were eaten

but i need help taking care of the ones i saved. right know i have a small container full of water from my tank with them in it, to keep the water warm i placed the container on a small foot warmer. what should i feed them? what temp should their water be at? does their tank need a filter? and what else should i know to properly take care of them untill i can get them a home?
thanks for your help.
