Hi all, I'm just curious if anyone has had yabbies and goldfish together. I currently have 4 goldfish, a beta fish and two yabbies, ( did have three. ) But one of the yabbies are completely physco! It attacked the smaller one and killed it, attacks the huge ass yabby (3x the size), attacks the fish. I've actually had to move it into our other tank as it almost killed our big goldfish. I know it's not guaranteed to live with other species, but the big yabbie will let the fish touch him and doesnt have a problem. This one just attacks everything.
