Well some bad news, I came back from vacation (was gone for a week) only to find both my GBRs missing. I checked everywhere, filter, caves, moss, etc... no luck. I asked my fish sitter about mid week how they were and she sent me a picture and they looked fine. I'm not sure what happened, all the params were ok when I got back. I did a 30% water change on Sunday and I am going to do another 30% today when I get off work.
I think they were, like others said, inferior quality and were not healthy from the start. I will steer clear of those for now until I find a repuatable breeder. I guess its all hit or miss in the fish world.
On a more positive note, I found another guppy fry hiding in my java moss. Only found one so far, one of the females gravid spot is still very dark, the other is much lighter than when I left.
