Golden spotted shrimp

My tank pH = 8.0
Can anyone tell me the water parameter suitable to breed this shrimp ?
- What is the pH ?
- Does the the larvae need brackish water ?

It's called Golden spotted shrimp here in Singapore.
Where does it originate from ? My LFS has no idea ?

Many thanks. :-D

This shrimp definitely belongs to the Palaemonidae family. It could be a Macrobrachium but could also be a related species (such as Palaemonetes sp.).

It probably needs brackish water for its larvae, but to make sure you should see how large the eggs if they start carrying eggs. If they have a lot of tiny eggs, the larvae will need salt in the water. If they have a few large eggs, then salt is not needed for reproduction.

Your PH seems very high. I would recommend getting it closer to neutral, but you'll have to see how your shrimp are doing. Some shrimp can actually take high PH values like that but most don't.

Thanks Mustafa.

I make a mistakes of putting freshwater gravel as a substrate.
Strange but it actually raise my pH to 8 even without coral chip.

In Singapore, many people use ADA soil.
It drop the tank pH to 6.5 or below.

Can I know what substrate are you using to maintain a low tank pH ?
Especially for sensitive shrimp like Bees and CRS ?

Thanks. :D

The best long term solution for lowering PH would be to throw driftwood into your tank. Make sure it's driftwood that actually releases tannic and humic acids into the water (most should be doing that). Sometimes companies advertise that their wood "does not discolor the water and does not release any chemicals" which, in this case, is a bad thing. Avoid those.

I collected my driftwood myself from the desert in Arizona. :) Works like a charm.

PS: What is ADA soil?
