Some aquarists wash this food with tap water using a fine tea strainer or coffee filter. When using in this form, try to filter out as much of the water the blood worm is kept in as you can. This is recommended due to the possibility of the water being diseased.
Feeding blood worms It?s also available in frozen cube format in the freezer section of a pet or fish shop. It?s Easy and convenient to use, as it comes in tin foil sheets. Do not keep frozen blood worm in the freezer for more than 6 months or it will go bad.
You can also get them as dried food packaged in small tubs.
Please note that this form tends to be the least nutritional. Plus as you use it up you’ll find it turning to dust as you get near the bottom of the tub. In this form it is only suitable for top feeders as it is nearly impossible for it to sink. So it is not suitable for Goldfish as they could take in air causing flotation issues.
Tetra sells them in a jelly form in small 3g sachets. These have extra vitamins added to the gel.
There have been medical reports that people can develop an allergy to this creature over time (takes 1 ? 2 years) just by touching it, breathing in dried blood worm dust or its contaminated water. A bad reaction (itchy or swollen eyes, coughing, shortness of breath, skin swells) to this fish food can build up over several years and you should be aware of this.
As with giving your animals any live food, there is the risk of adding parasites and diseases to your tank. Frozen, jellied and dried blood worm is usually irradiated to remove these dangers. But check the packaging.
