Close Mouth
Can bite you and other fishes because the mouth can close.
Cant bite, can bite, can bite.
When i free i try to take better pics of smiling mouths.
But I hope this thread shows clearly why some parrot fish cant cause much damage to tank mates, due to the shape and restriction of bite of their mouth. IIf this is not logic then i do not know what is logic. The mouth shape of this hybrid cichlid is another aspects which drives cichlid purists mad as well.
