What is a most likely cause of death of these RCS?
 
I haven't done anything new to the tank. At first I saw one dead and assumed it was a random death or a molt prob. Then I found another. One of them looked purple on the bottom of it's saddle. I don't know if they get dark when molting..I have only seen them look chalky before they molt.

The only things I can think of is that my gH is @17. So could be too hard maybe. I am currently bringing down the hardness with peat moss.

The only other thing possible is I have these microscopic looking worms (I have another post inquiring on this) and not sure if inverts are prone to parasites like fish. I have never had these wormy things...makes me want to do a 100% change.

They are younger RCS have only been adult for a few months. Other parameters are fine..other than the hardness.

i dont know a lot about shrimp, but i would have thought the harder the water the better? i did have a pet lobster once...haha
what's the pH? :)
if they are young, they're probably a bit more sensitive to everything - water params, parasites, etc.

go to a section of the site i.e. freshwater and tropical fish then scroll down till you find a 'new thread' button and click on it :-P

Their hardness range is 3-15 and ideal is 8. Just not sure there is a major problem for them if it is higher. They can also tolerate lower pH so they are pretty flexible. I just really hope its not the bacteria or whatever it is in my water. They are at a pH of about 7.5.

I am going to hold off on feeding too since a couple of people say they get worms etc from overfeeding..I do overfeed my snails. Never had any probs until now.

Not sure on the deaths, as I've also had a few in my RCS tank too. They have always been adults who passed. Pretty sure our water is the same, Vegas isn't too far from San Diego. I also overfeed my shrimp tank and I've got worms too. My worms have identified as Tubifax worms. Yuck.

Well I alter my water here with cuttlebone, liq. Ca, iodide & CO2. It's just weird because I have had them in a stable tank for months...the most recent thing was the worms..I just researched and looks like it could be planeria and something else..I don't think they are harmful. I just need to quit giving my snails a buffet every night. Makes sense because I have ridiculously thick substrate with a lot of food. No wonder I have worms.

When I think tubifex I think of worms coming from the ground..is that where yours were? My "flatworms" or planeria are on my walls and the other tiny things are just dust particles in the water. I don't know if those of the babies or something of the planeria.

How did you get rid of your worms?

planaria in a rcs tank is really common esp if the soil is the ADA type and there's overfeeding in the tank.one thing i remembered is the copper part.does the water come straight out from the pipe?? a copper head pipe head will introduce copper and other heavy metals into the tank. soaking active carbon before adding tank water will reduce the chances of getting any heavy metal in there. i do this before i add water into my main tank.my plants need the metals so it's impossible to add a carbon filter in the filtering system. i do this before as not to add any more metals except the ones that come in the liquid fert.

Yep, they reach up through the substrate, waving around. Totally gross. I sucked out as many as I could but this morning I see two or three of them waving hello to me. :-(

Did you get this resolved?

If you have planaria and snails, there's a chance that the shrimp are dying from ammonia poisoning. Planaria are a sign of overfeeding (and in direct relation to overfeeding, ammonia). And snails, when faced with excess food, will just excavate their bowels and continue eating... This causes more of an ammonia spike than excess food rotting on the tank bottom. Snails have a high bioload, and it gets higher the more they're able to eat.

Also, when you stop overfeeding, and the planaria start dying, they will also foul the water a little, so keep up your weekly water changes!
