I thought you were going to tell us you had bred them in your community tank!
I read an article ages ago by Nathan Hill of practical fishkeeping, discussing how amano's breed in saltwater or other, but he claimed to have bred them in freshwater. Bit of a curiosity
I was told that shrimps closely to amanos and sometimes sold as amanos do breed in freshwater. Not sure if this is accurate or mythology!
Amanos are currently going for 4 pounds each in my local shop!
