Apparently you can dive in your own tank.

This is a video of Defensive Back Roy Williams of the Dallas Cowboys.

He has a tank 8'x8' Round.

Within the first minute of the video you see his maintanence man diving inside the tank to clean it.

In the last 40seconds of the video you see Roy Williams dive in.

You have to watch a 30sec commercial before it starts but after that it's less than a minute to the tank and then fast forward to the end to see Roy dive.

Yup, my hand dives in my tank if it was bigger maybe the rest of my body could maybe when i build my saltwater pond :-\

it have sharks in that tank - and he not wearing any protected gear...
oh boy...
did catch what he said about his freezer? it is all for his fish food...!

 

[MikeNapoli]

I'm sure those sharks couldn't hurt him.

Especially when he feeds them as much as he does... his freezer was the size of a closet.

I counted 5 fish tanks. At least one was my size. (nano)

 

[waynes reef]

thats allot of fish food, that would be cool to swim with your fish though

Maybe that's why he's a terrible football player. He spends too much time in a fish tank.
