Amano shrimp help: yellow eyes

I got my first amano shrimp last Thursday, did a 1 hour drip acclimation, and let them loose inside the tank. They were very active and seemed happy to me.

The next day, 4 were sitting in the java moss I had put on top of the spray bar for my guppy fry. There shells had gone from translucent to semi-transparent brown, their eyes were yellow, and they were alive.

After spending the weeked away, when I came back and checked, a couple of them have started to get translucent shells again but all of their eyes are still yellow.

Here are my details and pictures as asked for in the stickey.

1. 6 amano shrimp, only ever see 4 at a time now.

2. Have had the shrimp 4-5 days from a seller on aquabid.

3. Neon tetras, black skirted tetras, guppy and 1 dwarf honey gourami

4. 20 gallon

5. Tank has been set up and running (after a teardown) for over 6 months

6. Tank was set up with tap water, but I've switched to re-mineralized RO water about a month ago for small water changes and evaporation. PH and KH have come down, but in all honesty I wasn't writing down my parameters for tank water until I started with RO.

7. Water parameters:
a. Temp: at work atm but when I check it's mid to upper 70s
b.
PH: 7.6
GH: 12
KH: 3
Nitrate: 40 ppm
Phosphate: not currently checking, will order kit
Ammonia: 0
Nitrite:0

c. The parameters were logged a couple days before the shrimp were added

8. Substrate is 6 months old, Flourite Black and Flourite Black Sand.

9. Heavily planted, dosing Seachem Excel.

10. No C02.

11. Lights on a timer at 10 hours

12. SunSun 302 @ 264 GPH, water is flowing just fine and have sponge over intake

13. Filter is new (2-3 weeks), and will be doing first check on it tonight. New filter set up with sponge and purigen from old HOB filter. Bio rings and floss (I think that's what it's called) are new.

14. Not using water conditioner atm

15. Haven't feed shrimp as of yet. Have no 'clean up' crew since I donated my chinese algae eater to the LFS, and the plants have been in there for a long time.

16. No changes as they're just gone in

17. Just sitting on the spray bar, but again they haven't even been in the tank 5 days.

18. Shells darkened and eyes went yellow.

19. Only see 4/6 together at any time, and haven't found any bodies. There's a lot of plants, and I added more rocks and java moss for them. Almost a jungle and they'll be getting trimmed tonight, so pretty hard to find bodies right now.

20. see pictures



Some other things that may be of interest after trying to read up
- I have seriyu stone, which I think may be why my GH is high. Stone has been in the tank for about 6 months
- I've been using purigen for the last 6 months
- fish are happy and active
- I don't have a TDS meter

Wish I could help you out. I also just recently got 5 amano shrimp and they are doing fantastic. Your water parameters are basically identical to mine
. Although my ph stays closer to 7.0 but not by much

Mine go place like that when stressed or too quick of temp changes, but I've never seen he yellowed eyes. Does it look like solid white mass inside the bodies as well? Could be bacterial disease. Sorry, hope someone has an answer.

Update: it seemed to have cleared up after a couple days. No idea what it was, but will run a few new tests on my water just to see.

how do you keep neons at 7.6? i can barely keep bristlenoses at anything below 7.

Sometimes you just need a little more cake.

I don't honestly know, they've been with me since the PH was 8.1, and after switching to RO water, with only little and careful water changes it's come down slowly.

I have amano and it seems to me that their color changes when they're preparing to molt. Whenever I see one looking particularly whitish, there's invariably a molted shell a day or two later. I haven't actually witnessed said molting, and since there are four of them I could be mistaken, but it seems like a reasonable guess to me.

Bump: As for the yellow eyes, I think they're reflecting light, so they'd look different depending on light conditions and the angle at which you're viewing.

Hoping that was it.

Update: Have only found a couple of them a few days later, but my tank needs a lot of trimming and moving around as it's almost a jungle in there, so hopefully the rest are 'dug in' and happy But the few that I've seen look good.

Thanks to all for reading and replying
