Hey I was wondering if any one had any ideas as to why my 3 female guppies are looking skinny and they hang around at the top of the water not doing alot. They have recently all had baby's so could this be something to do with it? My male guppies and other fish are all happy and looking fine. Here's a picture to show you. Any info would be very helpfull as I don't want to lose these cos they are really pretty female guppies.
