My albino grew to 18" in the first year, and was about 26" when he was killed by the ex at under 2 years of age. I kept him with, jau, rtc, tsn, Marble x RTC, oscars, bullheads, ect. He didn't bother anything that was too big for him to swallow. Constantly swam and was the first to eat. Fed him pellets on the top, and also frozen shrimp, fish fillets, ect. Awesome fish. Have also kept bullheads, stonecats, ect. Some members on here now with flatheads. Would like to get one myself.
