Hey everyone! I was just thinking about starting another tank, and was just wondering what the deal is w/ troph's? Seems like alot of the more experienced people here keep them....So what's so special about them? I know they are very nice looking fish, but is it their behavior? Are they really aggressive? What is it? Why so expensive? I geuss i'm just lookin for some info on em. It would be great to see a video of some of ya'lls.
