Hi Lainetti,
Sorry for replying so late. How large is your tank? And how large are the fish? They might not have enough space to form territories, and start fighting because of that. If they keep fighting I think you should separate them, as I fear the Zebra will loose this squabble.
I also wanted to say that I can understand that the language and spelling used by some of our non English members can tickle the funny bone sometimes, and a bit of friendly giggling will have to be ok when that happens. But it might be a good idea to include an answer at the same time, as the non English speaking member might feel he's simply being made fun of, and not being helped other wise.
We have a few members who's language is their second, and sometimes third language, and it's not always easy to get it right
