I admit I am being lazy and I expect this is already on this site somewhere but can't look through all the posts for it, but when I got my 3 lads the seller said worm them by putting the wormer in the water. She did not say how much! If anyone knows of an easy way to worm them I would really like to know please. If I have to catch them I will but they are just getting more confident and I would rather not spoil that by grabbing them if at all possible.
