Disapeering Shrimp Case...

[Skullkong101]

A month or two ago. I had got 30 RCS for a 10gal with guppies. I know way to overstoxked. But after a week they all vanished. I checked the filter. Nope. I checked under everything. Nope. I checked the floor. Nope. And they were to big to be eaten. 2 weeks later I found a single dead body. Now the question is what happened? All I can avoid it in the future. Note that tank is now replaced as it had a leak.

My guess is they died and got eaten, got eaten and died, or died and slowly decomposed. Could you have any pests in your tanks? I had some damselfly larvae that sneakily took out a decent amount of shrimp before I noticed them. Don’t underestimate the size of a predator’s belly.

Depending on how many guppies you have, your tank may not have been overstocked. Cherry shrimp have a minuscule bioload so you can have a lot even in a small tank.

If you didn't find them dried and desiccated outside the tank, they died and rotted inside the tank. Most likely because of high ammonia, nitrite or nitrate levels. Your profile says you know about the nitrogen cycle. Did you cycle your tank before putting the shrimp and guppies in it? What are your water parameters now?

Yes the tank was cycled. But I can't give you the parameters because that tank is no longer in use. I found a leak in it. But my 12+ guppies were doing fine all the fry were alive so it's strange.
