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
