Here's the deal, I bought a Baby Biorb from one of my brother's friends who never used it. Other than being a pain to clean, it worked great for Ghost, my DT. He swam laps every night and seemed to really flourish in it. So, fast forward to this weekend, the bottom is leaking! He's currently in my globe vase (looks like a giant fish bowl) which I scrubbed and set up. Don't worry, it holds ten liters of water so I think he'll be fine temporarily.
My question is, are there any tanks similar to the Biorb, circular, spherical? Or should I just look for something completely different?
