Hi!
I love goldfish. I have 3 fancies in a 55g (only like...1 more, then I'm done stocking - I promise!). I have tropicals too. However, my goldfish are my babies. They really have personalities, don't they? I hand feed mine, and now every time I stick my hand in the tank for maintenance, they eat me alive! Hehehe!
What kind do you have?!
Have a great day!
