Number of Shrimp Per Gallon?
I recently got 6 Amano Shrimp for my 38-gallon well-planted freshwater tank (~14 Zebra Danios, ~10 Corydoras catfish (2 breeding females), 7 Otocinclus catfish, 2 "Botia Salwnsis" loaches, 1 Cleaner shrimp, and now 6 Amano Shrimp).

I really like them, and they're doing a great job "mowing" my algae. I let the algae grown in a few spots, as my cleaner shrimp seems to like it. The Amano Shrimp are doing a beautiful job keeping these "algae gardens" from getting too large/tall.

How many Amano shrimp can I put in this tank, do you all think? Its fairly heavily planted, with tons of rocks/caves and driftwood, and the fish are all doing terrifically well. My Corys lay eggs 2-3 times a week (thank goodness the loaches eat them all), and even the Danios and Otos have laid eggs! I'd like to get perhaps another 6-10 Amanon if that wouldn't be too much. My ammonia is 0, nitrites are 0, and nitrates are around 5-10 mg/L.

i think you could have quite a few, i do not think they have much bio-load

You could easly do 1 per gallon, go and get some more :)

Up to 20 should not be a problem..Take care that they do not have space conflicts (not aggressive anyway) with the corys. It could result a bit crowded down there..

I never clean the back glass, and so it had a thin film of algae on it. Its actually rather pretty, with its filmy green color; that's one reason why I never clean it. The Amano shrimp LOVE it, and graze on the back glass like cows in a field! Its really fun to watch them. They also hang around (literally) in my large mass of floating Hornwort.

As a result, I rarely even see them on the "ground" near the Corys, so I doubt that will be an issue. Its a good point to bring up, though. My Corys get spooked occasionally and dart around like mad; if the shrimp were down there with them the Cory's could accidentally injure them. Luckily, the shrimp have found greener pastures! :)

kostanias right

they say a gallon per gallon for larger tanks, but remember, shrimp will fish if theres not enough room, and bottom dwellers wont like it either
