Subject: Questions about Whiteworms


I have been culturing grindal worms with great success for several months now but I am finding that they are too small for the adult fish I am feeding (tetras and barbs). I want to give white worms a shot as I understand they are the next size up.

My question is I have read that white worms require lower temps than grindals, between 55-68F. The space I have available is 72-75F and I am concerned that the worms may not fare so well. I have even read from several sources that the worms may even die above 72F.

I would appeciate your opinions and experiences with white worm and their temperature requirements.





The worms might not perish at say “73” but you will not find them multiplying much if the temp is over 65 or so. The refer is too cold and if you rig a refer with a new thermostat (from a beer making venture perhaps) you will burn up the compressor on the refer. It’s really not worth it.

However, we live in California and it gets pretty warm for long periods of time. We don’t see the 100s very often, but definitely into the 90 for extended periods. So what we do is…we culture the worms in Styrofoam fish boxes. We keep the lid on. The culture stays moist and dark and the worms love that. We put two 1 liter bottles of water into the freezer. When the weather climbs to the point where the temp inside the coolers is above 70, we take a water bottle out and put it into the culture. In a couple of days (depending on the temps) we exchange that now melted bottle with the other frozen one. The first bottle is now freezing…the second one cooling the culture. When the temps get really hot, we exchange the bottles every day.

In order to help ourselves a bit, we keep the cultures on the floor of the garage. The floor is the coolest place in the home.

This system has never failed us…every with the temp was over 100 for 10 days or so. My family didn’t do as well as the worms.

Take care,

    Beta Fish Facts…

    For any bowl under 2 gallons, clean it twice a week. If it is above 2 gallons, a weekly cleaning should be sufficient. Fish produce ammonia, and without an established filter to remove the ammonia, it will build up and eventually poison the fish….
