@bettalover. I don't think it was a "troll" thing for you to do, just something that probably shouldn't have been said. You DID apologize, and seem sincere in your apology, so I would say you are in no way a troll (: Have no fear. Just remember that a lot of people don't like it when their bettas, who they probably love a great deal, are insulted.
The best thing to do with trolls, aka ihatebettas, is to ignore them. When given no reaction, they tend to slink away, back into the swamps from whence they came.
Queen of hypocrites here, I rose to his/her challenge, and snapped back. I've been on the interwebz long enough to know better, and apologize xD From now on, I shall ignore him/her.
Edit: Sorry for the complete derailing of this topic! Sorry sorry sorry xD
