yes what good algae eating fish. This fish will eat all hair algae as well. I think their fins have a slight yellowish tinge. They are not as colourful as flying fox. i keep three big ones and one flying fox in a 125g tank. Beautiful addition to any community tank. They love hair algae. OH they cleaned one anubias from another tank that was full of hair algae. I would not set up a tank without them. They get big though. What fish!
