I was wrong in one of my previous post about it adopting a side to side swimming approach, because it's still heads down. They only go side to side in the morning for some reason and revert to heads down at other times. Feeding liquifry for filter feeders at the rate of about a drop a day(contains dextrin, yeast, pea flowers, egg yolk and etc). I don't see how this is for marine filter feeders only.. ingredients show it would work for freshwater fish fry too. The larger bottle makes it much more less irritating to deal with than egg layer liquifry! Not much morphological changes in the zoes. Some have grown like a half of a millimeter. Porbably the earlier hatchlings. Still tiny, but much more visible. I'm every bit the worried parent... don't know if they're eating.. too small to see stomach contents. It's white... so is it a good sign? It's always been white. They've also gained a much more visible 'spine'. It's a line of whiteness extending from head to tail. These used to be just transparent. I've read about them getting cannibalistic as it grows.. dunno if i'll have that problem. Time will tell. Water's getting a bit cloudy from feeding. A bit worried about ammonia and nitrite as there's no form of filtration. I would think about installing a sponge filter powered by an airline. Any ideas where to get a good small one?
