I received a plastic bag filled with culture medium that was a mixture of peat, coconut fiber and potting soil. It was enough to fill a plastic shoebox about 2 inches deep. I have since split the culture into two cultures. It contained all of the critters that were advertised. I will address each one individually.
First the grindal worms. I have found them to be very prolific and easy to culture. All my fish love them.
The earthworms have reproduced in the small culture much more quickly than i had imagined. I am able to feed them as a treat about once a week.
The springtails and "mites", I believe got into these cultures accidentally. My het formosa's and my Endler's like them. They float on top of the water when I rinse my grindals. I simply scoop them up and toss them in the tank where the fish munch them from the top of the water. I don't know if they have good nutritional value but the fish seem to enjoy them.
The DVD is pretty informative but it is about four times as long as it needs to be to convey the authors idea's. It's easy to lose interest before it is over.
In conclusion I would be perfectly happy with a culture of grindals and earthworms without the springtails and "mites". The grindals and earthworms yield a lot more food for the effort for sure. You may notice I put mites in quotes. This because the seller calls them mites but admits he doesn't really know what they are. I also raise Daphnia Magna. Now that I have gotten into culturing live foods there's no turning back for me. the fish seem healthier and more colorful. I have also found a great deal of enjoyment and satisfaction with the actual culturing process. I encourage anyone to give it a try. Your fish will love you for it!
