It is a dietary measure rather than a treatment, and persistent bloating in a fish needs the water parameters and the rest of the diet looked at as well.\u003c\/p\u003e\n\u003ch4\u003eDo I need to thaw the cubes before feeding?\u003c\/h4\u003e\n\u003cp\u003eYes. Ocean Nutrition's direction for the Nutris blister range is to thaw the desired number of cubes before feeding, unlike some of its formula cubes which are designed to be dropped in frozen. Ten to fifteen minutes at room temperature in a small container is enough.\u003c\/p\u003e\n\u003ch4\u003eHow much of a 100 g blister do I feed at once?\u003c\/h4\u003e\n\u003cp\u003eFeed only what the fish will finish within five minutes, which for most home aquariums is a fraction of a single cube rather than a whole one. Start with a quarter of a cube for a small community tank and adjust by what is left on the substrate after five minutes.\u003c\/p\u003e\n\u003ch4\u003eWill frozen daphnia cloud the water?\u003c\/h4\u003e\n\u003cp\u003eThe pack liquid is the main cause of cloudiness, not the animals. Straining the thawed portion through a fine net and discarding that liquid before feeding keeps the water clear and keeps the nutrient load down.\u003c\/p\u003e\n\u003ch4\u003eCan I refreeze a blister that has partly thawed?\u003c\/h4\u003e\n\u003cp\u003eNo. A thawed frozen food should never be refrozen, because the texture breaks down and the bacterial load rises. If a blister has gone soft, feed what you can use immediately and discard the rest.\u003c\/p\u003e\n\u003ch4\u003eHow long does an opened blister keep in the freezer?\u003c\/h4\u003e\n\u003cp\u003eOcean Nutrition does not publish a shelf life after opening for this product, so no figure is claimed here. In practice the limit is freezer burn: cubes kept in a sealed bag or container inside the freezer hold their quality far longer than a blister left open to circulating air.\u003c\/p\u003e","brand":"Ocean Nutrition","offers":[{"title":"Default Title","offer_id":55293355000099,"sku":"ON1591103","price":8.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/on1591103_1778651544_r.jpg?v=1786055778","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/frozen-nutris-daphnia-100g","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
