this is the first time raising guppy fry I have some that are 9 days old and some that are 3 days old. I would like more information on growth rates when they get their colors etc.. does anyone know of a guppy fry journal or growth/color chart. currently they are receiving 50% water changes every 2 days 12 hours of light a variety a food 5 times a day shrimp,blood worms, algae wafers, & tropical flakes there heater keeps the water between 78-80F I just want to make sure my fry are developing at the correct pace. also what is this I'm learning about guppies having bent spines? would I be able to see that visually and information on culling would be nice. any links, info, tips, or advice is greatly appreciated ! =] thanks in advance.
