i love goldeye they are a beautiful & delicious fish. ne1 keep em if so how big can they get in a tank, and what kind of params do they need. i sure would like to hear others exp before starting a tank.
By Goldeye are you referring to Hiodon alosoides?
If so these fish are not problematic to keep at all, but are a bit difficult to capture and transport. Care needs to be taken to not damage them and to keep the water cool and highly oxygenated.
Being a pelagic fish you do need a large tank with lots of swimming space. Feeding is not at all a problem and they take a variety of items.
