Tigrinus dont sift sand, they eat whatever hits it though. But can be fragile when young. Theres anot of controversy over how to care for them correctly but at the end of the day, they are catfish, scavenging anything around. Only difference IME, is that they are less aggressive then their cousins like tigers, or RTC. But they are $$$ so be prepared to spend a few bucks but to me, very well wortg it!! The colors and patterns are unmatched plus they get valuable as they grow too!!! Good luck!!
