The tank is a 360, which shows how big that motoro is. The black sand is estes marine sand and it works great, I have been using it for years. I would definately reccomend it.
i'd probably fight your atlantic ray if i was a motoro.
i'd be like
"YOU AREN'T ROUND, let's ray fight.
i'm gonna handle you, like i handled steve irwin."
The comment starts off a lillte immature, but funny and then you had to go there. I was in Bali when this tragedy happened, and I can tell, there is not one thing funny about that. The world is a lesser place now that he is gone. The amount of work he did for conservation alone is staggering. Not cool, not funny, not very sensitive of you.
