Wasn't sure if this goes under General Discussion or Breeding.

I just purchased 2lbs of Black worms. The instructions state to rinse with cold water EVERYDAY and make sure the water level is no more than 1/4" above the worms. According to the instructions, the water level is kept low so the worms can breathe and they ARE NOT TO BE FED.

.... The following are my assumptions: they are kept in the fridge as to reduce metabolism, thus lasting longer. They are rinsed everyday to clear the waste and prevent staleness (and also provide oxygen as the water is not aerated). They are not fed as the water quality would degrade quickly in small containers that have no water movement/filtration. The water line is low so the worms can physically "stick their heads" out and take in oxygen.

I have also read there are people keeping their black worms in tanks at regular tropical temps 75 to 80 degrees?

Could it be as simple as getting a 20 gallon tank....a couple of "cycled" sponges with airlines, feeding sinking food, and regular water changes as one would with regular fish?

Seems like the fridge method is simply to keep alive for 4-6 weeks while essentially starving the worms to death. Makes sense for the industry, as one would have to order on a continuous basis.

I am seriously contemplating of getting a tank, dump 1lb into the tank, and treat as one would regular fishes.....ie feeding, water changes, etc.


Anyone else done this? Makes sense? Ideally one can keep the worms for much longer periods of time AND have them even breed ...... can possibly even have a constant supply of black worms? Although, I'd be more than happy with just keeping them long term and THRIVING.
 
There also also topics on breeding them on Bing or Google.
 
Yes, you are on the right track. If you use a sponge filter, make sure it is a few inches above your substrate otherwise the worms will invade it and you'll never get them out.

Here is some great reading from our sister site Aquaria Central - http://www.aquariacentral.com/forum...9-My-Blackworm-Experiment&highlight=blackworm and http://www.aquariacentral.com/forum...-The-California-Blackworm&highlight=blackworm

Good pointer on having the sponge above the surface..... and wow great reads-- both threads.-- read them through thoroughly. Thanx!
 
I'm just a bit surprised, it seems not too many people keep their worms in an aquarium -- low cost, doesn't take too much real estate, and very easy to maintain -- certainly much easier than rinsing worms everyday! People I know who feed black worms to their fishes -- usually keep them in some sort of Tupperware in their fridge. Having them in a tank also allows feeding highly nutritional dry food, -- increasing their overall health/nutritional value.....and the possibility of breeding them is certainly a plus...... not to mention reducing the chance of getting a bad batch from the LFS.

IS USING A SUBSTRATE NECESSARY TO KEEP BLACK WORMS IN AN AQUARIUM? I understand the reason substrate is used, but I wonder if they would thrive just as well provided they are given enough food, good filtration, and regular scheduled water changes.
 
I've never tried to keep them in an aquarium without substrate. You could always try it using a small portion of your 2 lb purchase but I think the worms will still just ball up together like they do in the refrigerator. It would definitely be easier to harvest them in a tank without substrate.
 
I keep live blackworms in my 55. They do not breed! Although they have both sex organs just like any worm they dont breed,they fragment and regenerate. Black worms have between 150-250 segments and depending where they fragment they can regenerate a new head/tail...Substrate is recommended to make them feel safe...They will spread out and fragment like crazy,giving you many many more worms. Keeping them is as easy as keeping fish, just maintain the water quality and a good food source and they will be happy...
