Lis. 4,167 Posted December 2, 2014 I'd be tempted to guess that it's a Mayfly larvae? I don't know much about them, but I imagine they are predatory and may eat your fry 0 Quote Share this post Link to post Share on other sites

ichthius 122 Posted December 2, 2014 Definitely not a parasite. Mayfly sounds like a good guess. 0 Quote Share this post Link to post Share on other sites

hassan.zidan 43 Posted December 3, 2014 (edited) Today after usual checking for my goldfish fries earthen pond Hapa, really thousands of mayfly seen stick on the corners of the Hapa , and many beetles observed on the surface of the pond to gulping air and as i know beetles in the larvae stage is fry enemy . First do you think its not mayfly and larvae for some predators . Second how to fight all this predators specially the black beetles !!

Helen 8,511 Posted December 17, 2014 is it possible to apply netting to the top? you can add a few more posts or cross beams and throw a net over to keep the beetles out? are there any other predator like things that concern you? ie, opportunistic birds etc.. where the fish are, how deep is that point? 0 Quote Share this post Link to post Share on other sites
hassan.zidan 43 Posted December 23, 2014 Net applied but still beetles larvae seen . No any opportunistic birds except two big african Frog !! 0 Quote Share this post Link to post Share on other sites
