Mystery snail or algae eater

my briggs clean my tank so well I never have algae... I wish I did, I have to supplement. both tanks with snails are algae free.
 
I just plopped a heavily algae coated rock last night and was surprised four brigs really went for it and scraped them off completely. Poor nerites. Only the two were able to get their share of algae but they were outcompeted anyway. I still have a few more algae coated rocks for them to eat in the next few days.lol
 
how do bn's get????? i would like to get one for my 10gal.!!!


also is there a yellow veriaty out on the market???????



thanks
Ryan
