How is everything going, Cagney?

I cannot fathom your friend setting up 11 guppies in a 1-2 gallon tank! OMGahhhh that's horrible. I don't even consider it ideal for one little Betta, much less 11 guppies! I hope you've switched them to the 10 gallon. Even without a filter, it's 1000% better. You can get a Whisper internal or power filter (from Petsmart) for a 10g for around $10. Just make sure you do frequent (at least once weekly, at least 50%) water changes and keep an eye on the water stats. I agree, if you're going to keep all 8 male Guppies, keep only males in the 10g and get a suitable tank for the 3 preggy girls. I totally recommend getting them a big (5-10g) tupperware with a corner filter to birth in. To save some of the babies, you'll need to get breeding traps. Female guppies do well living alone, or just get a 5-10g to keep the females seperate from the males. That is way too many boys for 3 girls, and they should just be kept away from each other unless you're willing to swap 5 of the boys at a LFS in exchange for females.
