I am getting such a headache from trying to figure out what kind of tank to buy for my Betta. I bought an (expensive!) baby BiOrb but he seems to really hate the bubbles. Also could someone tell me about lighting? I heard that they have sensitive eyes? I contacted the biorb company and they suggested that I use the Biorb without the pump. That seems ridiculous as it can't filter the water. I just have no idea what to buy for him. Please help, he seems so unhappy, he sulks at the bottom of the bowl and won't eat. I will be using the BiOrb for a different kind of fish, although he is so pretty in there. I would be so grateful if someone could help. Thank you!
