I just got 2 guppies, 1 male and 1 female. When I got them home and put them into the 1 gallon aquarium that has some plastic plants and a small treasure chest, a couple of hours later I noticed that the female was giving birth! My first instinct was to put the fry in another aquarium so that the mother and the male wouldn't eat them. I put them into a 1.66 gallon aquarium with an under gravel filtration system. When I put the 5 guppy fry in the aquarium all but 1 swam down to take cover in the rocks the other stayed at the top rolling, the others were all acting fine and would come up occasionaly. This morning I found it dead (the 1 that had been on the top rolling). I can't find the others and I was wondering what you think happened to them. I can tell that the female is still gravid from the dark spot on her abdomen, and I was wondering what I could do differntly next time?
