also, i have been thinking, i have read in that same article that they have fed on other prey items (termites, small roaches, mealies and crix) but all died, longest survivour lasted 1 year. The ants they feed on have formic acid in them which gives them that horrible smell when crushed or annoyed. I was wondering if that is the chemical that they need to live and if it would be possible to get a supplement and be able to keep them alive on other food items?
