Exactly how nutritious are both fish and prawn eggs? I'm currently feeding a couple of purple anthias, P. tuka, a mess of Nutramar Ova, which they go nuts for. I know how hard they are to keep and have read up on them previous to the purchase. In addition to the prawn eggs, they also will eat anything that's really small (frozen rotifers and some of the scraps from Rod's food). No interest in NLS pellets as expected. Tank is fed 8x a day by 2 Eheim autofeeders (4x NLS small pellets, 4x otohime S1/S2 mix). I'm planning on implementing a feeder to dose a mixture of eggs and frozen rotifers 8x a day, but that's another subject. I want to augment the prawn eggs with some Icelandic capelin eggs. Why Icelandic? It's supposed to be more environmentally conscious with less bycatch and is sustainable. Actually stumbled onto a site that does sell a whole mess of eggs here: http://www.gourmetfoodstore.com/caviar/icelandic-caviar.asp?mscssid=NNJ9SMN66RSS8J49KWQ3A4P13GSC5MNE Now the question is, can anthias get by with just eating eggs?
