Japonica breeding habits
 
Anyone know anything about the breeding habits of Amano shrimp? While
looking at my tank this afternoon, my attention was drawn to some movement
on my Nutrafin CO2 bubble counter and I noticed a small, 1/4" long shrimp.
None of the 10 shrimp that I've purchased over the last several months were
that small when I got them, and they're all now between 1 1/2 and 2" long so
I can only conclude that some eggs hatched and survived.

The thing is that I'd always understood that Japonica required brackish
water to breed and my planted, CO2 injected, 6.6 PH, low carbonate hardness,
peat filtered (you get the idea) tank can hardly be considered brackish.

Any thoughts?

My large tank is med-hard water with ~6.8 natural pH and my amano
females are usually carrying eggs. I haven't seen any survivors, but
that is to be expected considering the number and species of fish in there.

My tank is not brackish and I now have *three* shrimp carrying eggs.

I think that there are 2 "algae eating shrimp" in the hobby, the C.
japonica(yamato numa-ebi to Amano ;) and another species. I suspect the
other species is what I have and is breeding.

As an experiment, I will be adding some phosphate to the water when I see
the first baby. I want to make sure they get enough to eat :)
