I think they are ok. I don't love them but I don't hate them... as long as the weird ones aren't deformed. Many have weird bodies (short bodies), many seem to have weird jaw structures (REALLY common in Arowanas it seems) and they just look off. I think when you start messing with the structure of the fish, either on purpose or not, it takes away from the fish as a whole and they look stupid.
