As stated above Fronts grow S*L*O*W. I bought mine as 1-1/2 smalls over 4 years ago. Keep the other fish close to the same size with similar disposition and things should be fine. I have 2 brichardi, a botia loach, lg royal plec, small common plec, a peacock pair and synodontis. All seem to get along very well sometimes the lg royal will get testy if one of the fronts has his spot but they soon part ways. Fronts are BIG movers so make sure you have plenty of depth or boulders for substrate.
