think they are real ive seen few diff pics of this dotted about , freaky aros , mine would be no good with two heads it'd be fighting with itself all day lol
I don't see a problem with letting it live. It clearly thrived enough to grow to an adult and it doesn't know its different than all the other fish. LOL
Same as Siamese twins in humans.
But I do have a huge problem with the fact they increased the price because its mutated.
