Red Cherry Shrimp repeating dropping eggs


Hello All,

I'm new to this forum and somewhat new to raising red cherry shrimp so sorry for the long post asking for help . I've been housing ~30 RCS in a cycled bare bottom, moderately planted, 10 gallon tank. The females are constantly pregnant with eggs but most, if not all, are dropping their eggs.

The temperature is ~72 to 74, pH 6.5, nitrites and ammonia are 0, nitrates ~10ppm, hardness is 50ppm.

Would RCS drop eggs due to the current being too strong in the water? I have a HOB filter covered with a sponge. However, most of the current comes from a bubble curtain in the back. It is strong enough that there is constant circulation but not to the point that the shrimp aren't able to swim easily through the curtain. Is the bare bottom amplifying the current?

Other besides that a few weeks back I went to visit a friend for a weekend and dropped in a 3-day feeder pellet usually meant for fish. I guess this was too much food for the shrimp and when I returned the sides of the tank were covered in white fungus from overfeeding. Since then all the fungus is gone, needless to say I won't be doing that again >.>

Current shouldn't matter. I've kept my cherries in my tank with my rena filter before and now they are in a divided tank with an aquaclear right and a big sponge filter.

Would you happen to know what could be causing them to repeatedly drop eggs :X?

Not sure why they are dropping their eggs, never experienced that with any of my shrimp, so I can't comment. As for the feeder, don't worry about doing that again for only a weekend. Shrimp can go a long time without feeding pellets. They can find a million things to eat in substrate or the plants. I routinely "starve" mine for a day or two without feeding pellets or anything else just to let them eat some natural stuff from the tank instead of pellets all the time.

Thanks for the help. I will generally not feed them one day a week to let them flush out their systems. I thought doing so for 2 days would starve them o.O, thanks for that clarification! I guess the one problem would be since its a bare bottom tank there isn't a substrate for them to look for stuffs in

You do have plants in the tank though right? Get some mosses, all kinds of little things will make the moss home and the shrimp will feed on that. I have lots of mosses for my babies to hide in and they spend their first week or so hiding in there eating little things they find.

Yes, I have mosses. I suppose I should get more to create more cover for the babies (if the females ever decide to actually go through with the birth)

My shrimp have dropped their eggs usually twice before they keep them. They are also brand new adults so maybe it's a learning curve they have to learn. I have noticed that the first time my shrimp carry they seem to have more eggs than they can fit under their underside. (learning curve also...not sure)

That too. read that sometimes first time moms will drop their eggs until they learn how to take care of them and what not. And yes, after each batch, they can seem to carry more and more eggs, more make it to term, etc.

I have heard that newer mothers will drop their eggs. I guess my main concern is that ALL the shrimps have been dropping eggs, including this HUGE one (~1.5") that is most definitely not a new mom (unless... it really is or something). I have had the shrimps for about 3 weeks now so it might be very possible it has only been their first or second pregnancy.

They're usually pretty adaptable to new environments, and if they are berrying (rather than having arrived berried) then you're good. They'll start holding onto the eggs in the next month and by christmas you should have tiny shrimp swimming around. It often takes them a couple of months to settle in and start reproducing in earnest.

The current shouldn't be a problem, but if it is, you'll see shrimp being washed around by it or all of the shrimp huddled in one tiny spot in the tank where there is low flow. I've got 2 or 3 culled cherry shrimp that I threw into my native river tank that are living just fine in a 55 gallon tank with 600 gph flow in one direction. They've managed to avoid being eaten somehow so far (it's been a month) though they have not yet reproduced.

Yup, even my cherries took about 4 months to start getting busy. A lot of that was me rescaping, doing too big of WC's, lots of other things. Now, that they are settled in, I have probably a 100 babies or so.

That's good news :]. Yea the shrimp are happily swimming around even through the bubble curtain (no problems even going through it). Glad I don't have to turn that off to keep up the flow of water in the tank.

My tank isn't a "barebottom" tank as I have substrate in it (black Eco-complete) with a number of plants & mosses.

The shrimp (cherries) forage around in the plants & substrate w/o a problem. When I first got them and the (new) adult females were berried over 85% of the fry were lost.

Could this have been from being NEW adults, NEW mothers, or just not settled in completely? I don't have a definite answer about these, however, since most of the females are now on their 3rd or 4th time being "berried", there are now much more fry in the tank.

Perhaps it was a combination of all three and not just one thing that caused problems in the beginning (new adults,mothers, & being settled).

My filter (Aquaclear #30 150gph) has a little bit of a current but the shrimp appear to "play" in the current rather than avoid it.


HTH,

Martin

I'm glad your shrimp were able to exponentially increase after their first few batches. Unfortunately for me so far not a single fry, heck, not a single egg that made it :[. I guess if I thought logically if the adults were swimming through the bubble curtain and around the tank it MUST not be that strong >.>

Thanks for the info
