Here is a fish information magazine site for info on the fish you want to know about. I Googled just like I told you to. It is loaded with info on what they eat, how big they get and how hardy they are. When it comes to research, you can't be lazy and just ask..You might as well learn to read up on critters now.

It's a very pretty fish, but reminds me of a goldfish. JMO
