Yes. There are shops selling Opae Ula in closed bottles as Eco system.

I got those too. But find it cruel and no breeding possible. Read alot and decided to convert into tank.
From 1 tank to 3... :smile: :smile:Addictive.

Oh that's interesting, what sort of price are the eco systems to buy or how much per shrimp to buy alone?

That's a great tank by the way!

My breeding tank parameters for reference:
Ammonia: 0ppm
Nitrites: 0ppm
Nitrates: 0ppm
PH: 8ppm
SG: 1.012 / 1.013
Temp: 24/25 degrees
Water: RO from the fish shop and instant ocean marine salt
Food: Feed once a week shrimplab's spirulina
Light: 12 hours of light a day


Just looking over your answer i would say you need to:
- Use RO water instead of tap water.
- Stop messing around and re-scaping the tank as the shrimp need their tank to be stable and undisturbed.
- Remove the filter and pump.
- Top up the tank to the top.

Your tank is also extremely clean did you clean the walls when you rescaped?

Thanks.
I will remove the filter for start. I will also slowly do water change with bottled distilled water. I didn't do any cleaning of the tank. There are 2 very hard working nerite snail in the tank.

You wont need prime or water de-chlorinators with RO/Distilled water. :wink:
