Thank you for posting this! Betta fish are so misunderstood, it's heartbreaking. We started off with a 2gallon tank for ours, but within a week he was in a 10gallon, and he LOVES it. I never would have gotten anything smaller than a 2gallon anyway for him because that seemed cruel even before I learned more about them (I have a great friend who taught me a lot about them!
) Unfortunately since we didn't change the water soon enough one time, almost 2 weeks (this was in the 10gallon, not the 2), he got mild fin rot from about .25 ppm
ammonia. So we treated him with salt in his original tank. Then about 2-3 weeks later, we waited 5 days to change the water (a bit too long clearly) and his ammonia was at .5ppm and the fin rot worse. Ugh! So we went back to the salt, this time a stronger dose (he is finished now). Now he gets about a 90% water change every other day until his 10 gallon is cycled. We weren't going to cycle it originally since it was just 10 gallons and we were going to change the water 30% or so each week, but after this mishap (which I am so upset my poor boy got fin rot, his tail looks awful! But he's very lively like he's always been, so he should be fine), we decided it was best to cycle it. He's been back in the 2gallon tank for almost 2 months now, maybe a month and a half.
He is such an active, smart little guy, I just love him! Eventually we are going to get him some pygmy cory cat fish friends to go in the tank with him, hopefully they will get along.
I called one pet store looking for heaters, and the guy instead of really answering my question (which was I am looking for a small heater for my betta fish), said bettas don't need heaters, they don't need heaters. Thanks sir, not going there!
What needs to happen is we need to educate educate educate! A friend of mine educated me, and I in turn have educated others too. The myths need to stop. These fish deserve so much better!
