I got 2 free Jewels this weekend, and I put them in my Malawi tank. It's a 90 gallon tank with a good mix of mbuna, and peacocks. I have read mixed reviews on the Jewels, with not much confidence in my decision to put them in this tank. What is some of your opinons? Are they going to get banged up, or can they hold there own? Some of the posts I read made it seem like they will be more aggressive than most of the mbuna? Any truth to this?
