If anyone out there has tried using a Rosy barb(s) to rid a tank of thread algae, I'd like to hear the details. My 55 gallon heavily planted tank currently has a light/moderate thread algae infestation and I've been told by a couple of people that Rosy barbs eat the stuff. Thanks for any information, Matt P.S. Thanks to those who answered my question about Thiel's chunky laterite.
