Couldn't believe it--Petsmart for $7.99. Its between the size of a ping pong ball and a baseball! I expected it to be MUCH more expensive. They only had two left, so I took the one that was more round. Its very green and healthy looking. Its obviously real, as it looks just like the real ones you can Google, and it sunk after I squeezed it out.
When I squeezed it out, there was no stink, and no dirty water. Question is, I have it in QT in a 1 gallon tank. The water from the pet store went in, and I and topped it off with dirty tank water from a water change I just did. Anything else I need to do? How long do you recommend QT? A week? Or more?
