My guppy just had fry again - 3 of them and pretty large in size. However, I will only see my tank once every 4 or 5 days for the next 3 weeks. I've used weekend feeders for the adults (yes I know they foul up the water, but I do 30%-40% water changes when I replace them), but don't know if the fry can eat this too? If so, it seems that weekend feeders can be a really simple food for fry, especially for people who can't do feedings several times a day every day to raise them. I haven't found any information about this, and was wondering if anybody has any experience with feeding fry this way.
