gar man;4865659; said:I swear to you on all my aquariums that it is 8.5", I've had it since it was .25" long. I'd take it out and measure it but its a bid stressed by beeing beaten around by the channel cat when I was removing him along with everything else in the tank cept the Bluegill to take to cabelas. Once she settles down a bit more I'll prove it to ya.
I'd just line up a ruler or tape measure in front of the tank and wait for the fish to swim by it.
Have you thought about changing the lighting to something less bright to bring out the fish's colors?
