Ok, i've been reading through the threads here and i'm a little confused. Im currently planning for a 125 wide with a senegal, peacock eel, and an african knife. I want something that will swim on the top/middle of the tank, and devour any extra feeders i have, cause i'm breeding convicts. I originally wanted a red belly piranha, but after going through the threads i saw a pic of 5 in a 125, and it looked like they barely fit. I just saw a shoal of piranha's at petsmart, and they didn't seem that big. Do they grow that big, or was this a different type of piranha? Is there a small type of piranha that would work here? If not i think i've found a decent substitute, from what i've read charax gibbosus would work well, but they're hard to find.
