I'm looking for a new centerpiece fish for my 29 gallon. I have a small school of Burmese border loaches, a small school of rummynose tetras, an oto (I need to replenish that school) and a couple of cherry shrimp running around (though I have no idea how they've escaped being eaten by now!). I've had dwarf gouramis in the past and they're a contender but I was also thinking about possibly a betta. They're so pretty but I wanted to see what other people's experiences or opinions are on their compatibility with what I already have. I wouldn't want anyone in the tank to be stressed! Would a single male or a couple of females work in this setup? Thanks for your input!
