hi, i'm fairly new to bettas, i've had this little guy, tenchi for over a year now, keep him in a 2g tank with filter, but still change the water every 2 weeks, feed him 5 hbh betta bites 2x daily and it seemed to work for about a year, then in the past month i've noticed him becoming bloated... he still swims around happily, makes bubbles and such, but hes just becoming noticibly bigger on the front part of his body (i'd say in a month his stomach area has bumped out to about 3/4 of an inch) and its beginning to worry me alot, just wondering if anyone has any suggestions about what i may do to help the poor little guy out
