How long do they take to get to full size?
I have added five new WCMMs to my cold water tank. One died on day one, the others are fine but I am nervous because size-wise Dave the Goldfish could certainly eat them if he wanted to. They are about 1.5 - 2cm long at the moment. How long before they hit the 3cm mark?
My two old fellas seem to be quite happy with the newbies so far which is nice :)
