I think you really love your beta, and want to do the best for it. Your beta tank is way to small, a beta is a big fish, and can.t be happy in such a little space to live. Think, you have to live your life in a space, as litte as a airplane toillet. I'm sad to say it, but in this little tank, it will not live a long time. Just search at google about taking good care of a beta, and you'll find lots of instructions about the size a tank should have. It also needs a filter, to get all its waste out of the water, and keep the water fresh and clean, places to hide, can be rockholes, or high plants, so it feels save. I'm absolutely not judging you, some petstores don't care of they sell proper envirements for the pets, and don't give always the right information, they only think about selling. Others really take care, and give you a really good advise, as they all should do I think. I think your little fellow needs more space, some gravel on the bottom, a few plants, en places to hide. It is a tropical fish, so a heater would be nice, and a filter is really needed. If he gets this, I'm sure, you'll have a happy beta, wich has enough space to show all his beauty, and even is gonna come to you wenn you're near his tank. (sorry for my bad english :-)). Wishing you all the luck and lots of joy with you're betta.
