How about emperor tetras for your 265? They have more interesting behaviour than most tetras and will breed in a community tank. They are slightly territorial but in a tank that size there would be room for lots of them.
I have my heart set on a 265 of my own next year, so I was happy to read about yours. Thanks for sharing.
Hey, I am wondering if you can help a newbie start out with a fishtank? I will be getting a 52 gallon Juwel tank, PM me back if you are willing to help me pick the right fish, equipment and things for it.
