dahling8 97 Posted April 10, 2018 I have several small indoor cultures of daphnia for my other tropical fish tanks and never bothered feeding daphnia to my sub adult goldfish. Just thinking that it's too small to make it worthwhile. Does anybody feed live daphnia to their adults? I have to harvest daphnia anyways, the cultures have a die off so if it's worth feeding to the goldies, I'd rather make a separate culture just for the goldfish. 0 Quote Share this post Link to post Share on other sites
