You have selected one of the best tropical fish foods available. You will find that your fish will be healthier and maintain their true colors. Our California Blackworms are the perfect food for conditioning new tropical fish and breeding tropical fish.
Upon the arrival of your Blackworms, thoroughly rinse them with chilled water (40-50°F) until their runoff water is clear and clean. We have found that untreated tap water works fine. When placing them in your live Blackworm keeper or other container, make sure that your worms are no thicker then 1/2 inch. If they are thicker, they may suffocate or try to escape from their container. Keep no more then 1/2 inch of water above them. A container the size of a shoebox works well for one pound or less, and a sandwich size Tupperware container is fine for 1/4 pound.
Keep your Blackworms in the refrigerator. They need to be kept between 40-55°F. Do not keep them in an aquarium, outside boxes, basements, etc., only in the refrigerator.
To keep your worms fresh, they should be rinsed at least once a day. Use only chilled water when rinsing. Do not use aquarium water or room temperature water, only cold 40-50°F water.
We have found that the biggest issues with keeping blackworms alive for several weeks stem from a few things: lack of cold, lack of daily rinsing, and keeping them in too much water.
Most customers have no problem with the refrigeration or daily rinsing aspect, some have had problems with keeping them in too much water. This being the case, we have a short pictorial rundown of how we keep worms.
This is a picture of a couple of pounds of worms just the way they come from our refrigeration units before rinsing:
These bins are 12"x22", 8" deep, and capable of holding 5 pounds of worms. You can see how little water they are actually kept in by the previous and following picture:
Rinsing with cold tap water, this is how they look while still swirling around before settling:
After about a minute, they all settle nicely to the bottom. This is when you can tip the container to drain off the water. This picture shows about 5" of water, which is way too much - worms need to breathe too!
Tipping out water, there is still too much:
Right about here is where there is just enough water, which would bring us back to the first picture:
You do not have to feed your worms, as they will live off their own body weight. However, the longer they are kept, they will lose weight. Uneaten worms will not foul your aquarium, but do feed according to your fish and aquarium size.
Our California Blackworms (they are not tubifex) are farm-raised in the best of conditions. They are not harvested from ditches, duck ponds, factory runoffs, or hatchery ponds. At various times of the year, different types of worms and flatworms might appear mixed with your Blackworms. These are not harmful to your fish.
Thank you for choosing Organic Blackworms, hope to be hearing from you soon!
