Yes, the fish is deformed.
You also have 2 different variant of frontosas in there. The lighter colored one is a burundi frontosa, the darker one looks like a Zaire variant. They should NOT be bred together. The frys will be hybrids and no longer valuable. They might get deformed stripes too.
if u were in sydney - i would give it to u since u like it so much...my parrots are peaceful...they all get along...you say the larger one is a Zaires? i brought them both as 6 bar frontosas...
i think the zaires variety is expensive here in oz...
The lighter colored one with the black stripe going across his eyes is definitely a burundi. The purplish colored one is not a burundi. It has the black zorro mask on its eyes. The mask does not extend all the way down to the bottom of its mouth. It is either a Zaire variant or a Tanzanian variant. Which exact variant, I can't say. Without knowing the collection point its nearly impossible. I'm leaning more towards a Zaire variant because of the deep purplish color.
