Blackworm reproduction by fragmentation?

I recently purchased a little over a pound of black worms to start keeping a larger quantity on hand for rearing larvae. After getting over the initial hump of die off and fouling as I tried a few different setups, I now have a good quantity doing well in an aerated bucket with no sign of dead worms on any given day. I seem to have found a feeding and water change schedule that is working well.

Since they hit their stride, I've noticed a huge quantity of worm fragments in the bucket, which appear healthy and I presume are the normal means of reproduction. Does anyone else have input on what an actively reproducing blackworm culture looks like? I just want to confirm that this is normal and not an indication of stress or some other variable out of whack. I've kept smaller quantities of black worms before in different setups but never noticed this rate of fragmentation. I've never quite matched this combination of water quality/temp/feeding/oxygenation before.

Thanks!

Yes. They also breed through eggs like regular worms but seem to do fragmentation more in unnatural environments.

Blackworms are Easy - The Reef Tank

I found that forum thread extremely helpful last year when I had blackworms. They went well for months until my babies all grew up and I got slack about water changes.

Blackworms reproduce either sexually or asexually but in captivity they almost always reproduce asexually - by breaking off a section of their own.

I heard sexual reproduction is very difficult and impractical in a captive setup, and there seems to be no huge benefit or disadvantage for either methods as live feeders.

The blackworms come in different at different times. My last batch also had lots of live fragments or small ones. The water seems to foul a little faster with this batch too. I mostly just rinse and use them. I've had mixed results trying to feed something to the worms.

I've had good luck feeding them Hikari algae wafers for many years, but never really quantified how their population changed as a result. The fragments were not in the worms when I received them, but like you say it may be a seasonal result not directly attributable to this maintenance regime.

    No, I havent. Im not really sure why he wont eat. Hes in a 1 gallon tub and still a juvenile. When i offer food he swims away from it. Does he need some extra time? or is this something I should be worried about.

    Hello everyone! I’m new in this world and i need some advices please! I have 2 axolotl babies and currently the water from the tank is from bottled water ( all parameters are good) but i want to change 50% of the water with city tap water. My question is how to change it? Do i need to get axis out, do the change, add the prime, wait (how much?) until its dechlorinated or i can add the tap water directly into the tank with axis in it, and add the prime conditioner? Thank you!!

    1. You dont need to take them out of the tank to change the water as long as you pour it in slow as to not rattle them around too much

    2. add the prime to your tap water, for most conditioners the consensus is 5 minutes of waiting time

    3.After 5 minutes it should be safe to add

    Hello I'm wondering if fridging axolotl is necessary when giving it a salt bath? My fridge is unpredictable it just changes from freezing temperature to melting by itself. And driving me crazy. So I would not be keen to put my axie in these because of the sudden temperature changes it may experience. Can I leave him in a clean dechlorinated water tub in some of the room? Would I then need to refrigerate the salt water ? Or would I just keep it in a same room temperature?! I have everything ready for him to get a salt bath but just wanted to check about this fridging before I do ( waited for approval to join the forum:)

    FYI I noticed a white fluffy strings on his gills yesterday. And looking through the forum and some pictures it looks like fungus .
