I just went all over Petco.com and spammed their .5 gallon tank reviews with this:
I need to correct quite a few things that rookies to betta fish need to know... bad information means a badly kept betta fish. D:
First of all, Betta fish (mostly known as Siamese Fighting fish) are not from Japan. This is a common mistake, though... They're native to Thailand, so they're used to warm temperatures. Thus... they need a heater. 80'F is an ideal temperature for them. And to those concerned, no, this isn't too hot.
Secondly, Betta fish love bigger tanks because it's more room and there's more to explore. In their history, it's said that they lived in puddles, but they aren't the stereotypical puddles most think of... They live in rice paddies, which, as a person can imagine, has knee-deep water and about 550+ gallons of water. Lots of space.
It's also been proven that animals are smarter the more they can see, explore, etc. Fish are animals, so obviously it applies to them.
Bettas are also very sensitive to ammonia... and living in a .5 gallon means ammonia from what they eat and what they release from their bodies builds up fast.
I've been taking care of bettas for a long time. I have five right now, and I'm getting another two in a few weeks. The smallest tank I have for one of my males is a 1.5 gallon. It still might be small, but I do water changes every two days and he has a heater that keeps him at a comfortable 82'F. If I had a chance to get a bigger tank, I'd jump on it. 3 gallon is acceptable. 5 gallon is ideal.
Betta fish show that they are happy by building bubble nests, coloring up very well, even changing colors or their fins growing out longer. They'll really become active in both their environment and the environment outside the tank.
If you really love your betta fish, save the money for something bigger... At the least, a fish can be happy in a 1 gallon with lots of water changes. And you can also add more neat underwater decorations too!
Be smart about betta fish, and do your research thoroughly... they can live up to 8 years if well-kept.
Maybe I missed a few things, maybe I said too much. Lol... but basically I was saying that a .5 gallon is NOT acceptable (unless, of course, it's a tank for pictures only or during water changes). Hopefully those who are looking for a "neat, stylish, modern, fit-anywhere" tank will see my review and think about researching... or at the least, getting a bigger tank.
So who's gonna join me? =D
I had too much time on my hands tonight, lol.
But hey! One review a day helps bring awareness to first-time owners, right! Think of the bettas we'll save!! 8D
