Product Description

Seasonal shipping notice: Due to high temperatures commonly experienced during the summer months and freezing temperatures during winter I am not able to guarantee live delivery on live cultures at these times.  For customers in urgent need of cultures and willing to take a chance I will still continue to ship cultures upon request.  As a general guideline... microworms and vinegar eels tend to ship well at temperatures between 1C (34F) and up to a maximum of 30C (86F).  Grindal worms between 1C (34F) and up to 27C (80F).  White Worms are the most heat sensitive and ship best between 1C (34F) up to a maximum of 20C (68F).  Daphnia, Moina, Brine Shrimp and Rotifer eggs are safe to ship at all temperatures. Please keep in mind that the temperatures in a mail truck or mail box on a sunny day may be significantly higher than the outdoor air temperature.

This offering is for a starter culture mix of worms and culture bedding packed in 4"x3" breather baggie. There will be 100's of grindal worms giving you a great start for your culture.

Grindal worms are one of my favourite live foods. I use a lot of these worms in my hatchery. They get fed to everything from two week old fry to full grown adult fish. They thrive at room temperature and when you set up your culture correctly you will be absolutely amazed at how many worms can be harvested every day. They do best in soil or coconut coir around 1" deep and kept damp. For food quick oats or rice bran are both very good.  Sprinkle a small amount of food on the surface of the soil every few days and then place a tile or piece of glass on the surface of the soil.  When the culture is established the worms will collect on the underside of the tile making them easy to harvest. 

This item ships for free.  Canada shipping only.

  1. Easy live food 5 Star Review

    Posted by on 16th Feb 2022

    Took about 3 weeks for one package to grow to the point where I could feed a small amount to my fish every other day. Another month or so after that and I had enough to feed 50 or so CPDs daily. The fish love them!

  2. Easy to cultivate 5 Star Review

    Posted by on 9th May 2021

    As stated, it takes about a month for the culture to take off -- and when it does, it's prolific! Most of my marine fish love them and I've even seen them being consumed by corals.

  3. Grindal Worm Cullture 5 Star Review

    Posted by on 28th Dec 2020

    My Grindal culture took off after introducing the starter to a plastic pan of coir. It took about a month to really get going. Easy to grow at room temperature and seems to prosper in any plastic container provided some ventilation is added. White bread moistened and dipped in spirulina powder is a favorite to gut load before feeding.
