well to start off i have a 10 gallon guppy tank with a few small cory cats and a quickly growing number of snails i had 9 beautiful guppies in it but 4 have died from what i dont know, i cant figure it out. I changed the water after the first one died of a sudden and now about every week a perfectly health lookin fish just dies i cant figure it out because there are about four babies fishies swimming around. i thought if something would be really wrong the babbies would die first. if anyone has any clues or suggestions please let me know
