Title: Doesn't do the job and terrible for bettas.
Review: I got this to divide my 10 gallon tank for my two bettas. First and foremost, the holes in it were way too small. It caused a huge temperature difference in the tank, and kept the filter from working on one side. Secondly, my bettas could see each other and my more aggressive one became very stressed out incredibly fast. Third, it didn't fit right in my tank and somehow it got loose. The next thing I know I have my shy, reserved betta venturing into my very, very aggressive fish's side. I managed to rescue my little guy before he could get anything more than a good chasing. Thankfully, I had a 3 gallon that I set up rather hastily to house my shy boy.This divider didn't work for my tank, and it could have got my betta seriously injured or even killed had I not been home at the time. Save yourself the money and build your own divider.
