Here's the story on these guys. They were laid, hatched and became free swimming in a twenty gal. with mom and dad. After a week of free swimming I moved all the fry into a ten gal. Filled with water from their original tank and the filter from their original tank. Skip ahead three weeks and they are growing like crazy, but so is the ammonia. I don't think the filter is keeping up. I have an 80 gal. bow front set up for a grow tank but is it to soon to put em in it? Oh ya they are angel fry.
