Everytime I get new male guppies they seem to die rather quickly. Females that I have had seemed to have come out unscathed. This time I lost both male guppies along (within a week of getting them. seemed to get a white fungus on them) with 2 adult females and numerous young guppies as well. I have 1 lone female guppy left and an albino cory cat. Also I have no substrate or test kit with 2 rooted plants, 2 moss balls and java moss. I have an in tank filter which seems to suck and clog up quick in the cartridge, 10w cfl bulb, and algae on everything except for moss balls and java moss. I do plan on upgrading to a large tank as soon as I can.
