In the past 6-7 months, I have been through 3 small aquariums for my betta, Sammy. The first one was a plastic tank from the local pet store, which came with a lamp and a pump to circulate the water. Unfortunately, it developed a crap and we had to toss it.
The second one was an open top glass tank with no circulation or lamp. However, it quickly developed some sort of infection. I put a small heat pad in (his water was sitting around 66 degrees F and went up to 78 with the pad) and added the medicine recommended by the pet store, but it didn't clear up. He became less active, and had a recurring problem with his swim bladder. And, unfortunately, the stress deteriorated his fins some.
So, my fiance went out and bought the same kind of tank as we originally had. He's much happier now (dang high maintenance betta), but this tank has also developed a crack. I think the tank is called a Mini-Bow, though I can't remember the brand. Anyone else had problems with these tanks cracking on a consistent basis? I take the lid off regularly to feed him and change his water, but make sure to put it back on carefully so as not to damage the tank. Lot of good that did.
So, what would be a good tank to get? I'm looking at no more than 3 gallons, and would really prefer a lamp and pump. I saw one called an Eclipse, which is right down my alley. Are these decent tanks? Any others I should consider?
