LionStorm - I think by TROLL they mean someone posting comments so ridiculous they can not be legitimate and are only doing it to waste everyones time. Like a pratical joker.
PS - Princess Silly, what ever you do, DO NOT get a Mandarin. I am brand new too and do not generally give advise, but even I can tell you without a doubt that it will die. We all make mistakes learning this hobby and the fish pay the price, but knowing this from the outset and buying one anyway would be nothing short of criminal.
Let us know what you decide and if you really are serious, this board will help you every step of the way. Just make sure you take it slow and understand the 'cycle process' before you go any further or every fish you buy will certainly die. Also, never buy a fish without researching it first - a lesson most of us learn the hard way.
