Hmm.. Well thanks for the info. Cause yes, of course - Petco said it would do fine in some small bowl or similar. I just happened to have the 1 gallon and thought maybe it would like more room. Ive been told that too big of a tank will stress them out and kill them? Apparently i need to do some more research. :)
really if you got a nice 2.5g plastic bowl (9 bucks at petsmart) it would be a cute, perfect little home for your betta and you would only have to do a full water change 1-2 times a week. A heater would be great, too
Some bettas don't seem to like big tanks, but we are talking BIG tanks in that case, like 75 gallons or so. Could be, like Doggyhog mentioned, there is too much space and not enough cover. Bettas like a plant or some sort of place they can hide in.
Yup, I definitely agree with everyone :) The natural environment of the betta is the densely planted race paddy fields of Thailand where they have a vast expanse and volume of water, but a LOT of cover. In any size tank, if you don't provide enough plants and caves your betta will feel exposed and stressed. Bigger is always better, just make sure you have enough plants and decor for him to hide in so he feels secure ;)
Yeah thats way off. I know people that have bettas in 75 gallon tanks.. healthy, happy bettas at that. The bigger the tank the better.
Yeah, when I got my fish his colour was whitish-yellow, and he hardly moved, and after a day of his 30 gallon tank, he started swimming around way more, and he still does, and now his colour is pink-purple.
