Hi there, just joined this forum as I'm relatively new to shrimp keeping and I'm having an issue that has me stumped. For context I have a dedicated tank (5 gallon) just for some bloody mary neo caridinas. But over the last few weeks since I got them, they have been dying one by one and I find them literally in pieces (I've attached photos as reference). I have no other fish in the tank except some tiny snails and I cannot see any form of parasites (not even a single scud) in the tank. I've estimated I lost around 10 of them so far.
Here are my water parameters: FYI I use RO water with Shrimp King mineral salts , I only top off water when needed and have avoided water changes for now as the TDS is stable at 180PPM
- TDS 180
- PH 6.5-6.6
- GH 6
- KH 1-2
- Zero ammonia, zero nitrites and zero nitrates
- Temperature is steady at 21 degree C (room temp with no heater)
- I have a sponge filter and a eheim compact filter that has a net so that shrimp don't get sucked in.
- For a small tank its very heavily planted with driftwood and lots of moss and plants
I think the PH maybe a little soft for a neo caridina but I cant imagine its lethal? I can only assume its molting gone wrong (which is why they're in pieces). If the water is so bad I thought that they'd die en masse? But it's always been just one at a time, max 2. I even have one female that is berried and I'm extremely anxious that something is going to happen to her.
Any help or insight would be helpful as I cannot diagnose what the problem is.
I need an explanation to what has happened to me ... today, some beautiful Black Panda came home, they were all alive and very active, the water temperature inside the bag was 19.8 degrees Celsius so I started the acclimation with the temperature leaving the bag floating in my tank but open for oxygen exchange (the bag was a breathing bag, is this an issue? It was open…).
In just 30 minutes the water reached 23.5 degrees (could be this an issue?) so I started with the drip to match the parameters of the water and only half an hour later there was a dead shrimp, after this death all start to die in a period of 2 hours.
The substrate is Glas Garten (PH 5.8 max), I use Bee Shrimp GH+ (TDS 130 - GH 6), I checked before Ammonia, NH2 and NH3 and all were in zero. The shrimps came with a PH 6.8, GH 6, TDS 155.
Two weeks ago, I was doing some maintenance in the tank and I broke one small hydrogen thermometer dropping all the small metal balls in the water, so immediately I sucked all the balls with a pipe removing also a big amount of soil. Could this thermometer poison my water? I took some of my Neocaridina shrimps in a bag and I added this water and they look fine, why the pandas died?
Should I set up the tank again from zero?
