Is this white mark on her cheek normal?

Sorry about your betta.

I keep amanos in a number of tanks and have for some time. As far a breeding any of the shrimp we might have in a tank, amanos are some of the most difficult because of their early life cycle. They start out in FW and then need to migrate into water with salt. Then they will need to be returned to FW. So they naturally spend different parts of their life in different salinities. I had a friend who was trying to breed amanos with some success. I always had some which were berried and she would come over and take a few of them. The next time she brought back a few of her successful results and some of my fms and took away a few more berried gals. She had a low survival rate which I consider a real success for a hobby breeder.

You should be able to get the salt out of the water faster than very slowly with a lot of small changes over time but also less rapidly than doing very large changes in a short time span. Somewhere in between makes the most sense to me. I would start with about a 1/3 change. Then wait a couple of days and do this again. This will mean you have removed about 57% of the salt. From there I would just do normal weekly 50% changes. If your tap parameters tend to be fairly constant then 50% weekly goes a long way to keeping ones tank water stable over time.

After the first weekly 50%, the salt will be down to about 21% and almost 10% after the second weekly. I doubt the shrimp will notice any of it. I do not have any intention of trying to breed amanos and mine have lived in 100% fresh water for many years.

The above assumes your source water is fairly stable and the parameters are OK for the shrimp and then for whatever new fish you end up adding.

Ah that's really interesting thanks, I didn't know much about them, maybe I can do the salt removal slightly faster then, I think I'll try keep it pretty slow tho :)
