What is wrong with Tigers and the Blue worms?
There is nothing wrong with any breed of worm but all breeds differ in breeding and eating patterns, For example, Tiger worms do not breed as prolifically as the Reds, and the Tigers also like colder conditions and prefer not spend as much time in the very top surface area. The Blue worm is a very hot tropical worm that breeds very prolifically but it also has a shorter life span. It is very hard to breed in consistent volumes all year long because of its breeding patterns and consequently its numbers tend to fluctuates greatly.
