I bought him from someone of craigslist for $50 and he didnt have barbels when i got him, the guy said it got bullied so he lost them but im hoping with some time in a peaceful tank they will grow back. My tank is 120 gallon ( will get a bigger tank when my lil buddy gets bigger ) and the heater is for 90 gallons. My LFS didn't have one for my size tank and that's the only one they had that was closest to 120 gallons so i bought it to test it out and it heats the tank pretty good. Tank stays at a steady temp of 78
