Hi! I have 2 goldfish and a common pleco in a 30 gallon tank. The pleco's 5 inches long and I don't think there's enough algae in the tank for him so I drop algea wafers in but the goldfish get the wafers first. Are there any foods the pleco will eat that the goldfish won't? I had a pleco die once for no apparent reason and I am starting to think he starved because my goldfish are voracious eaters! I have tried to distract them to one end of the tank with flake food while the algea wafers go in the other end but they eat the flakes in 3 minutes and discover my poor pleco's dinner and start eating that 2 minutes after that. Do any of you have any ideas? My pleco's changing colors and looking grouchy these days and I am concerned about him!
