What do you guys make of this behavior? (short vid)

[Andy Sager]

I origanally had 2 red tailed sharks in the tank cause the woman at the store was like "oh yeah they get along fine..." So now I only have one.

Now you know why. ( and that the woman you spoke to doesn't know her fish as well as she should so you need to be a little more cautious of what she tells you. )
