ok, so we're picking pu the new addition soon, and i am relocating our ball to a tub. I was just wondering what size tub i needed to go and get.He's about 3 foot, approx 800 grams. We've got a 55 gallon aquarium for the RTB, and thats only until the custom tank is done, at which time the ball will go back into the 55 and the RTB will go into the custom. I just need a temporary spot to park the bp, and a tub would be cheapest right now. Thanks
