Amanos are AMAZING. I have a tank that was cycling and started to grow green hair algae on my rocks and substrate. A TON of it on my rocks. I added 9 amanos and overnight, nearly all the fuzz on my rocks were gone. Substrate was cleaned as well. Not 100% of the algae was cleaned off but a majority of it was eaten up over one day.
9 amano shrimp in a 40G breeder tank.
They're amazing, now I know why Mr. Amano uses them! I highly suggest in getting amano shrimp if you're looking into algae eaters. 2 will be enough for a 10G. 4 if you have a ton of it. 2 if there's only a little.
