i just bought a royal myself hes doing great though he is a real pooper. i have had him for a week, hes been doing some mager munching on my drift wood which are african drift wood and a local piece from our lake which i boiled the heck out of. however this weekend i finally saw him sharing zucc with my albino gibby. hes getting fat and eating alot. so make sure you give him veggies too. a well rounded diet will make him grow to his full potential. my new royal is only 3" i can't wait to see how he turns out in the years to com :O)
