I've mentioned tilapia more than once before in this topic but never red tilapia (红罗非鱼 -hóng luó fēi yú). These are not, as some food websites which should know better claim, a different species but simply regular tilapia which have been selectively bred to be red skinned and with pinkish red flesh.

They are also widely regarded as being more healthy eating as well as better flavoured than the regular colour. Given the blandness of regular tilapia that would not be surprising. They are, in addition, almost scentless, so ideal for those who find 'fishy' smells off-putting (although that usually indicates lack of freshness rather than any inherent quality of the fish itself).
They are becoming increasingly popular, but are relatively expensive. I buy them as fillets at around ¥50 / $6.88 USD each, which is expensive here. Regular tilapia are around half of that at most, often much cheaper.
