they don't always have yellow bellies, some times the color fades out on some fish

The first pic is more in line with the ones i've seen in person.

I'd be really peeved if I spent the time growing them out to find out they had little to no yellow. Good thing to be aware of.

be careful. ternz are found in venezuella and brazil.

the brazilian form is much more yellow than the venezuellian variant, which is more common on the market. brazilian terns usually sell at a more costly price. the one on JP's second pic is def one of em.
