How many amano shrimp for a 125litre?

[typicalalex1]

Hi guys.

I have a 125litre tank and i wondered how many amano shrimp i can get in there?

It is quite heavily planted, there is a lot of java moss, some cabomba, rotala, blyxa and 4 medium swords (will eventually reach the top of the tank).

I have a lot of filtration for this tank, i have a All Pond Solutions(think its called sun-sun in the US) 1400EF filter, which delivers 1400litres per hour.

Fish - 7 harlequins, 5 penguin tetras, 4 dwarf neon rainbows, about 8 BNP and a couple of corys.

I have 5 amanos at the moment. I have had them for about 2 weeks and they are doing great. They were hiding a lot at first but they are always out now. I have found 2 empty shells so far so they are molting fine.

So how many would you suggest?
