Hi A while back I had a pregnant guppy in a community tank, so I placed her in a breeder box. However she got sick and died. Now I have 10gal tank just for guppies, and one of my females gave birth inside the tank. I don't have a seperate tank for the fry, and didn't want to seperate the female again, being afraid she might die. I provided hiding spots and plants in the tank for the fry. So far some of them have survived. I thought I would be ok with things working this way, but I worry all the time that they will make it. I want to start using the breeder box again, but first I want to find what my problem was the first time around. I have this breeding box: . Could it be that I put her in there too early? Or maybe I didnt put the breeder box deep enough in the water, so the water didn't circulate enough? Her scales got kind of mouldy before she died, almost like they were melting (sorry that's the best way I can describe it).
