Trying to find out the kind of green macroalgae in the tank. Sent to me with Opae Ule and Chaeto like algae. Multiplying in Opae’Ula tank, got them in the Amano shrimp larvae tank for nutrient uptake. F3 larvae seems doing very well at zero nitrates. API tast kit said is zero or close to Zero. Want to keep the nitrates at zero. Latest experiments in water quality management. Also have a DIY Denitrifying thing on the other side of the tank.

Grazing Amano shrimp larvae on their way to shrimplets in a week or so.

Moving on to F4 and testing the Alkalinity and Calcium. Dosing carbon to keep the chaeto and phytoplankton alive. Nitrate 5 to 10 ppm. PH at 8.4.
Dosing bioculture and hopefuly the new setup will get a better result.

A group of berried Amano shrimp having a mass spawning after a 50% freshwater change in their tank.

Larvae look good after reduced the calcium in the brackish water by 200 ppm. They will not survived calcium at salt water level. They’ve less transparent and theirs shell thicker. A mixed of week, couple weeks old the some are halfway to F4 shrimplets.

If I could get my false amanos to breed, I'd really like to try this with them... but I probably need to get some more shrimp before that happens... Still in awe!

You’re right about needed extra false amanos shrimp to try breeding them.
The way I breed Amano shrimp by generation, I may run out of berries Amano shrimp to keep breeding unless I can find a way to increase the survival rate. F1 and F2 are not much different in berries size compared with wild caught F0 shrimp. From F3 on, the Amano shrimp getting smaller and hatch out larvae getting less. Unless they are getting easier to breed, I may hit the dead end.

Refer to a old video and refreshing my memory about the vid that I took at Sept 11, 2018 on breeding F2 and record where was the salinity level in breeding them.
Bred f2 at ppt 22 to 24.
F3 was similar to F2. Though should be trending lower, didn’t see much different.
F1 ar 30 to 34 ppt.

After some experiments on the first 3 F4 batches failed. I think I found where the salinity for F4. Sorry, more videos. If they morphed into shrimplets in a couple weeks, F4 larvae may have adapts to even lower Salinity level at 14 to 16 ppt. Wonder where the salinity level for the next generation if there is one.

If they are, it can be a great example of how breeding animals can alter them in a short period of time - even if it's something as simple as a behavior change. (for better or worse)

One F4 larvae about to morph into shrimplets. Red color disappeared and when the swimmerets fully functional and developed, they will begin racing to freshwater shores.
