Some people do not think beta fish can live in a community tank. The trick is having a big enough tank with non aggressive fish to co habitat it. Beta fish are top swimmers, neon fish are midswimmers, and plecos are bottom feeders. So long as your beta has enough room and is not over crowded or roomed with aggressive fish (like gold fish or angel fish) they do well with community tanks. I am an experienced beta owner, and through my experience betas in community tanks live longer than betas in their own tank. The oldest betta I've owned lived to be 4 , almost 5, years old and lived in a community tank very happily. This is a newer family member, Nebula. He is a double tail Male about 6-8 months old. Though he is a recent addition to the family, he is filled with personality and loves to spit bubbles!
