Not true. 1- they're all hand fed. 2- I honestly can't tell that they are weaker swimmers than the others. I feel like the ryukins are the slowest actually.
huh. that IS interesting. i would have thought the downturned bodies and lack of dorsal fins would hamper their swimming abilities significantly.
i've only ever had ryukins, and they've varied greatly in their swimming speed and agility. some of them like to shoot across the tank like fat little bullets, while others prefer to just bumble along all lazy-like. one, however, has an enormously fat little belly, but a very stunted tail (he's golf ball sized, but his tail is barely bigger than a betta's) and he actually WADDLES through the water. it's so cute to watch!
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
