Thanks! I might get a used 3 gallon at a good price. Not sure yet though. Is the 5 gallon footprint much larger? If not, I'll strongly consider it, especially if I buy new. If I buy new, the 5 gallon is actually cheaper than the 3 gallon on Amazon. Go figure. Do you have the hex or the corner 5 gallon? It seems like the hex has a better feeding door but I'm not sure if it's good for a betta to have so many angles and reflections. Is that a bad thing?
BTW, my husband found our betta upside down resting near the top. This seems very odd and I've never heard of that. He appears fine otherwise and eats with much gusto. So not sure if that's some circus trick? Or if my hubby made a mistake? Anyone else see this? I did a 100% WC today and added the hydor mini heater, which quickly heated it to 79-82 so I unplugged it. I'll definitely be getting a better heater when I get the new tank but this one was only $6.50. I'll just have to keep an eye on it.
