I just bought some feeder guppies from my LFS. They are small but with amazing patterns, pink, neon green, yellow, etc. They don't look quite as nice as the regular guppies I've had in the past in that their fins are kind of irregularly shaped. Possible that it's because they've been neglected and raised in the feeder tank. I do hope they get a bit bigger. They are all about 1/2" or smaller. I got 8 male and 1 female. I don't exactly want a tank full of them but would like to see what their babies look like.
I've been looking online for the expensive Endler's. Thanks for the feeder guppy idea.

This is _way_ cheaper - 16/$1.
