Mal and Beth Davidson live in Australia and raise blackworms for aquarium fish. If you live down under, you can order live blackworms. The rest of us can order freeze dried blackworms. I know several people who have used them and think they're terrific fish food. Mal recently worked things out so he can ship to the States and use popular credit cards. With the present exchange rate, price and shipping are about one third less than stated. I'm going to try them and register an opinion.
If you want to do your own test, you can ask for a free sample at
www.blackworms.com.au. Be sure to tell Mal you read about it on myaquariumclub.com.
Well, the email address didn't work this morning. I'll check into it.
