Goldfish, goldfish, where for art though, goldfish?

They must just be wild ones, I guess...?

I doubt that it's anything stressful or disease-related by your description, Deniz.
 
duh!

I know that!

They're wild rebels and they go behind the rocks n plants and do naughty things back there. No wonder I took'em out of the community tank and gavem their own, they're bad news! :p
 
I'll leave you two to your repartee...

Interestingly enough, there is no "wild-type" for goldfish as they were created from the Crucian Carp (Carassius carassius) and artificially evolved to their current specific status (C. auratus). Fun fact for tonight! :)

How many goldfish do you have in your 10 gallon tank. If you have more than 1 it is overcrowded. 1 per 10 - 20 gallons of water would be good. I would think that the are stressed. I know I made the same mistake when I first started with my goldfish tank.
