Yes fronts get really large and have a lot of girth to them when they are fully grown. They will eat other fish but pellets are much healthier for them. Is it a good deal? possibly. It depends on the breed of front and health but for $10 its hard to go wrong. I also suggest a bigger tank that little fella wont be little when he gets grown up so save your pennies and get yourself a 55 or larger. Fronts are good in groups, but remember its either 1 or 5+ to a tank otherwise they can fight to the death. Good Luck with the fronts!
