Thanks to the help I received on this list, my grindal worms have been growing very well on polyfill for a few months now.
Now I have a few questions. My first question concerns harvesting. Do you find laying an acrylic sheet on top of the media the easiest way to harvest the worms?
Here is a link to my Fish page and the with out dirt culture pictures: http://inkmkr.com/Fish/LiveFoods/WithOutDirt/index.htm#10
I have been just collecting balls of pure worms that congregate at the edge of their food. Since I use green Scotch Brite pad as the top layer, I can see grindal worms really well.
However, I sometimes end up picking up their food, too. I have a few acrylic sheets that I can use to collect worms and I am wondering if laying an acrylic sheet makes it easier to collect the worms.
My second question is about the frequency of media cleaning/sub culturing.
How often do you clean the poly fill sheet?
Do you just throw away bottom layers of poly fill and start a new culture by using the top sheet?
I see a lot of tiny brown dots in the media. They are not moving at all. Are they poop? Do grindal worms have egg capsules/cocoons like earthworms do?
I need to start a few new cultures at the moment.
I inadvertently contaminated a few grindal worm boxes with microworms.
Microworms seem to be outcompeting the grindal worms for food and grindal worms are now climbing the wall.
I am not sure if grindal worms are looking for a new home due to the shortage of food or space.
Their media seems to be getting foul quickly after the microworm invasion.
Your help will be greatly appreciated.
