I bought a tank and stand from Craigslist and when I got to the person's house, they wanted to give me two common plecos and a stripped Raphael catfish with the tank. I've had multiple tanks in the past, but they all had artificial decor. I want to try my hand at a biotope tank. Would this work? One site said there'd be no plants at all, just rocks and driftwood, but another said it would have at least 6 different species of plants.
