well, I already have the syno and the shark. All the top 6 listings. I can try to have my brother take them. His tank has 2 gouramis, 1 rainbow shark, 1 kind of goby, and a school of black skirt tetras. but he doesnt want to risk his gouramis, that happen to be mine, because of when my fish had ich. Which was a month ago, and they have been fine sence then.
I do know the tetras are nippy to angels though. But there are 6, wouldnt that turn down the bitting?
I also have to keep the shark, and the syno in my tank though.
