Wooops hit return there by mistake,
Aye anyway, I recently bought a new guppy to keep my other one company, the lady in the pet shop told me that the males have more of a fanned tale than the females and a generally more colourful, when I started thinking about it I said that I had a male so I got another male so I wasn't going to get any baby guppies, but when I got home I noticed that my other guppy looks totally different to this new one, when I introduced them they got rather frisky and where chasing each other everywhere and now all the other guppy does is sit at the very top of the tank, it occassionally goes down to swim about but then it goes back to the top. Now I am wondering if this is a characteristic of a guppy that has a bun in the oven. She seems well so I dont think she is ill. Any ideas folks?
