butterfly fish

[Canadian Man]

Here's a funny Copper banded butterfly story for you.

So EmilyB has a brain coral and a Copperbanded butterfly named Cooper. Cooper picks on the brain coral in EmilyB's tank so she sells the brain to Canadian Man. Canadian Man get's a bigger tank (230g) and buys Cooper from EmilyB. Same brain coral and fish go into Canadian Man's tank and Cooper doesn't even look at the Brain.

As you can see, much of the same info Deepblueaquatics told you. Flip and coin
