Yes, I also suggest lots of water changes!

Goldfish are VERY dirty fish and with so many of them in a small tank they're bound to get that tank very messy!

I'm kind of suckered to them though, as they were the first pets i've had for years. They even gave me a little baby one year!

I love the black ones. I had a black one for a while, named Nelly (he was POTD once! ) but sadly he passed away.
