atyopsis moluccensis My bamboo shrimp died after a molt and I don't know why

[homulilly]

Hate that this is the first topic I have to post but I haven't been able to find any answers.

 

I got a Bamboo shrimp (atyopsis moluccensis) about 4 months ago and things seemed to be going pretty well. It molted the first time a couple months ago without and problems, and spent all day sifting food from the current. The only times I saw it picking at the substrate were when I scared it off it's perch while doing water changes/cleaning which seemed like normal behavior.

 

It molted last night so I didn't see the process but obviously something didn't go well because When I saw it this morning it was alive but its carapace was deformed with, for lack of a better term, large bubbles or cysts on each side lifting it away and leaving the gills exposed. The poor thing lived for a few hours after that but eventually died while i was busy trying to find any information on this. I'd noticed the ph creeping up a bit this week (think it was about 7.4 or 7.5 at the highest) so I put some seachem neutral regulator in and did a small (about 5%) water change the day before and I'm worried that could have caused it. Additionally I switched from using seachem equilibrium to saltyshrimp shrimp mineral about a week ago for maintaining hardness. I use RO water.

 

I had one cherry shrimp kick the bucket this week but I believe it was just old.

 

This is a 20g community tank with 12 chili rasboras and a colony of red cherry shrimp (about 50-80 individuals)

 

Parameters:

Ammonia/Nitrite: 0

Nitrate: ~10

pH 7.0-7.2 right now, was higher the day before

GH: 5

KH: 2

TDS: 250

 

Other stuff:

I dose seachem flourish and iron/potassium/phosphorus about once per week each and have a couple almond leaves in the tank i swap out monthly.

Any information or advice would be appreciated. I'm pretty devastated right now.

Same thing just happened to me.  Same tank size, more or less same population.  Large bamboo shrimp successfully molted and came out beautiful orange.  Died two days later.  Water chemistry checks out fine.  Temp 75, Ph 7.3, no ammonia or nitrite.  Any ideas anybody?

This is happening to my bamboo shrimp right now. He molted and looked fine after but now two days later not eating and not moving. Sitting under a leaf. I don’t think he is going to make it.
