That places them between rotifers and bloodworm in the frozen range, and makes them a workable food for small community fish and juveniles that cannot manage a whole midge larva.\u003c\/p\u003e\n\u003ch4\u003eWhy is the protein only 2.3%?\u003c\/h4\u003e\n\u003cp\u003eBecause frozen daphnia is 96% water - the highest moisture content of any food in the range. The figure is measured as fed rather than dry, so it is not comparable with a flake or pellet. Among frozen foods, 2.3% is genuinely low, and that is what makes daphnia a light variety food rather than a growth food.\u003c\/p\u003e\n\u003ch4\u003eIs daphnia a treatment for constipation or bloating?\u003c\/h4\u003e\n\u003cp\u003eNo health claim is made for it here. Ocean Nutrition's own positioning is that the hard chitin shell provides roughage through the gut, which is a description of the food rather than a remedy. A fish with a persistent digestive problem needs its water quality and overall diet reviewed, not a single food substituted in.\u003c\/p\u003e\n\u003ch4\u003eCan daphnia be the only food I feed?\u003c\/h4\u003e\n\u003cp\u003eNo. It is a single unfortified ingredient with no added vitamins or minerals and very little protein, so it belongs alongside a fortified staple rather than in place of one. Two or three feeds a week is a sensible share of the diet.\u003c\/p\u003e\n\u003ch4\u003eWill small marine fish eat it?\u003c\/h4\u003e\n\u003cp\u003eMany will take it, but Ocean Nutrition positions frozen daphnia as a freshwater food and that is how it is specified here. For a marine tank, the frozen marine blends and rotifers are the intended products.\u003c\/p\u003e\n\u003ch4\u003eDo I need to thaw it first?\u003c\/h4\u003e\n\u003cp\u003eYes. Ten to fifteen minutes without water at room temperature lets the cube break up so the individual daphnia disperse and drift.
