I have a bunch of 3 week old Jack dempsey fry that i need to get rid of. I have been throwing them in my angel tank and the angels love them! There is 7 angels in the tank and they are about prebreeder size now. I threw in about 35 babies today and they were gone within a minute. I dont want them to get sick from eating too much though. How many of the fry can i feed a day? I have about 200 fry still left to go...
