Has anyone ever introduced a Chinese Algae Eater (Gyrinocheilus aymonieri)
into a pond? with koi and goldfish? According to a few websites, they are
herbivores, but apparently develop a taste for small fish as they grow
larger and are fairly territorial.

I'm curious develop a taste for the slime coating of the their tank/pond
mates the way plecos (Hypostomus plecostomus) do? Koi-lo don't bother
responding, I can google just as well as you can.
