Do different species of roaches have much of a difference in nutirional variety? If so is it enough of a variety to make breeding something other than the dubias worth it? Thanks in advance.
I have found that one roach type will happily and readily eat gutload items that other roach types arent eager to eat. So YES they can be nutritionally different, due to gutloading differences at least.
And I agree with pssh - my chameleons enjoy eating different things. The look of a dubia is very different from a turk or hisser. This adds interest.
