Can someone please give me some useful advice about guppy gestation. Have one female and 9 males (yes, lucky girl) and am relatively new to the world of fishies. Have noticed her size has almost doubled in the last 2 weeks and now a large blackish red spot has developed near her backside. If someone knows the telltale signs that the birth of the little 'fry' is approaching please share your wisdom. I have a breeding (floating) tank but I don't want to put her in too early or she might stress and abort or become ill and weak. Thanks, K.
