get a black! i dont have 1 myself, but i will when i have the room. Dont have to worry about the drop eye and they just are way cool.. Silvers from my knowledge get bigger, faster tho.
the hardest part is losing it because you have a huge catfish that eats everything. They dont mix well unless the aro is huge and the catfish is small. Other than that they are fairly easy if you are a average fish keepers
