RCS won't breed?

Hello,

I've had my 7-10 RCS in a Fluval Spec 2 for a few months now and they haven't bred yet and I'm confused as to why not. I'm wondering if the tank is too small for them to breed?obviously they don't need a lot of room but I thought they were supposed to breed all the time but I've only ever seen eggs once (which got stuck in the small hole in the back that I didn't notice at first). I have a good mix of males and females and they should be comfortable.

The temperature is right, there's plenty of moss, and no co2. I feed them shrimp pellets made by fluval but I don't know what else to do.

I'm wondering if moving them to my 10g will encourage breeding or not? Thanks!

Your aquarium should be fine. I've bred them in a 2.5 gallon myself with no problems.

Perhaps your shrimp are just too young to be breeding?

Just keep at it, and you will eventually see baby shrimp; RCS are like the guppies of the shrimp world

When are they old enough to breed?

My parameters are fine, I checked them two weeks ago, however I do find the occasional dead shrimp every few weeks but I don't know from what.

My water might have a lot of iron in it though, will that deter them from breeding?

Parameters 'are fine' doesn't help us help you. pH, GH, KH, TDS, Ammonia Nitrite and Nitrate readings are needed. Otherwise we can spout off info all day long as to 'the things that cause shrimp not to breed or kill them' but it will just be tossing out answers.. How often are you doing water changes and how (vacuuming substrate or no, etc)? How big were they when you got them? If you saw eggs somewhere in the tank and not on a female, then you've obviously had a dropped egg issue. Which can happen due to stressed mommas, first time mommas, unhappy in the tank, and whacky params.

They are old enough to breed when you start seeing saddles on females. Some take a couple of months to mature, some take longer depending on temperature of the tank. Which we also don't know, just that you said it was fine.

Sorry!
Ammonia and nitrites were 0, nitrates were 5. Unfortunately I don't have a way to test for the other things. I do a water change every week, about 30%. I don't vacuum the substrate because its sand, I figure that my MTS will take care of anything underneath it. I usually take a solo cup's worth of water off the top.

As far as eggs, I saw them under a female once but they disappeared, like I said I think they got sucked into the filter, which has since been covered up.

The temperature is about 79 degrees.

I think that answers your points!

If you are making a post for shrimp help without listing ph/kh/gh, then its safe to assume these water parameters are ungoverned and left unchecked. These are absolutely critial if you wish to keep them as pets.

Was the tank adequately cycled? What are the ammonia, nitrate and nitride levels?

If you seek help, provide enough information for others the opportunity to.

How do I test kh or gh? I remember testing the pH when I tested the other parameters but I don't remember the results. I will have to test player today when I'm home.

It's basically to measure how hard or soft your water is. Different shrimp need harder or softer water and they all need calcium along with other elemental minerals in order to grow their shells to molt, so if a shrimp like neo's are kept in very soft water, they don't usually do well because there isn't enough calcium/magnesium/etc in order for them to grow their shells properly to molt and breed. As well,babies molt a lot, so they need proper water too. Shrimp like crystals need softer water, and too much gh/kh can cause their shells to be too thick and they can't molt, so knowing hard or soft your water is, helps us know if it's within the proper ranger for cherries or not.
