Well after reading the posts on this site i realized that i would need something bigger then i have. unfortunately i was talked into buying a very small dual hex betta tank that is maybe .7 gallons. I thought to myself that it seemed very small but was convinced they would be fine so i bought two beautiful fish and put them in between the divider and realized they barely have room to swim. I have a few questions. what are the noticeable differences in keeping them in a larger tank? do they grow bigger and brighter? or are they just more happy in general? I had two ideas, one was just take out the divider in this one and get another one and put them in two seperate ones to themselves, would this be good for them? Or i could possibly afford a 3 or 5 gallon tank at this time BUT only one, if i did this is there an easy way to make my own divider or a cheap one to buy? Any help would be greatly appreciated! thanks!
