algae and swordtails

[JL15219]

Just read this article http://www.thekrib.com/Fish/J-floridae.html

Has anyone ever had any experience with swordtails eating this much algae?
Please let me know..

Many live bearers will eat algae, but it is a minor amount.

seems unbelievable that they will eat that much
