Campbells are much
smaller than Syrians and live in colonies. Unless you are planning on
breeding, if you decide to offer a home to Campbells make sure they are the same
sex otherwise you could find yourself with a lot more than you originally
planned. They are relatively friendly to each other, although sometimes
fights do break out, especially if the dominant female is challenged.
If one is being picked on and is injured you should move them into a cage of
their own, but do not be too hasty in separating them in case it is just a
squabble. Once separated, it is unlikely you will be able to re-introduce
them at a later date.
Campbells have a reputation of biting humans, although
it you're lucky you might find one who is very friendly. My first
experience of Campbells was very good and I was fortunate to have a very
friendly one called Flossy. I automatically assumed that all Campbells
were this sweet, it was only when I agreed to foster a mother and her babies
that I discovered that Flossy was a rarity. The mother would spit and
hiss at me even when I went near the cage.
