Red cherry shrimp stopped breeding.

My red cherry shrimp seem to have stopped breeding. I don't see any babies at all where I used to see dozens on the glass and plants. I use RO water mineralised with Equilibrium. I've checked the TDS and it's 225. I don't know if I'm overfeeding/underfeeding or what. Its only a 10 gallon tank so should I be doing regular water changes? Has anybody any ideas on what could be the cause?

What have you been feeding them?

 

The females need protein to produce eggs. Lots of protein.

Try feeding them more frozen bloodworms, at least once a week.

Cherry chrimp are very simple to keep usually. There will come a time when they reach maximum occupancy as the tank can't support anymore, how many do you have in a 10 gallon tank? 

Has anything else changed in the last 6 months as all seemed to be doing well? Feeding a bit more may help but be careful as it is easy to overdo and that could really mess everything up! As JayC, what are you feeding at the moment?

Thanks for the help guys. I feed them a home made food that I found online, it contains bee pollen, Spirulina, Chlorella powder and other stuff I can't remember. I'll be sure to get the frozen bloodworm on Monday. The number of shrimp has definitely dropped so I'd estimate there are only about 50 in there now, down from maybe 100. I can see loads of exoskeletons so they're still shedding, which I guess is a good sign.

Let us know if it makes a difference.

There is another thing you can try ... 100% water change. Then readjust the parameters back and reacclimating the shrimp into the tank. Being careful to not kill off beneficial bacteria - that means keeping the filter media and substrate in water the whole process.

An old tank can loose all a lot of minerals, or cause a build up of a certain waste that normal water changes won't (completely) get rid off. The occasional 100% water change can bring back these lost minerals, or balance that waste product to a more reasonable levels.

A full water change could also simulate fresh rainfalls for the shrimp.

I do that to my tanks once a year. It also gives me the chance to rescape or replace substrate.

in my experience...less is more..let em chill.seems to me...even RCS much prefer stability...and are much more resilient than much advise would allude.  Though I have had my struggles.  I find it is virtually impossible to underfeed.  with a few plants especially.but easier to overfeed.  good luck.

Update: changed the water and all seems to be going well. A few days after the water change I noticed 4 or 5 babies on the front glass but I haven't seen them since. Do I need anything special by way of food for them? I let algae grow on 3 sides of the tank and feed Bacter AE now and again. When I first started with this tank they bred like mad, I had dozens of babies all over the place. I have one small Corydora in there with the shrimp.

Woo hoo!! 

Great news. I'm glad the 100% water change worked.

They are probably hiding.

Keep feeding Bacter AE by syringing it directly into clumps of moss or under hiding spots.

Thanks for the tip Jayc, I have just been sprinkling the powder on to the water. I'll use the syringe from now on.

You're welcome, and either a syringe or a pipette will work to get the fine food particles directly to where the baby shrimp are hiding.

Fantastic news, as JayC states, they are probably hiding as all babies do, so there may be more than you think! Still, any is a good step forward?

There may be enough biofilm in the tank with the Bacter AE as well so you don't probably need to feed extra with only a few baby shrimp. If you start getting lots of babies then you can use this baby food which I used to use - just get a pin, dip it in the tank about 5mm, then into the food (powder), knock off excess from the pin, then swirl the pin in the tank and the food should get to most of the tank. Most foods I always use less than they recommend! The amount as aove it wouldn't hurt to use even with only a few babies, I'm sure adults will eat it as well, so if you do get it I would start when you get it but only dose as above and maybe every other day!

The package is deceptive as it is a piece of card with a couple of mm of food on top, having said that if used sparingly it lasts a long time, I only ever bought 1 and it will likely be postage free as it can just go in a normal envelope? You will need to find a small container from somewhere to put/keep it in.

      Great idea! Please document your journey here. I have no experience with marine shrimps, so cannot help you. But what you have listed above seems like a sound plan to get started.

      That sounds like a fun project and look forward to hearing how it goes!  Hopefully someone will have some useful advice/tips etc?

      I have an idea. And considering I’m terrible at being concise, I’m sure it’s gonna take me a while to explain it.   Essentially, I want to do a nano marine rockpool tank, with just crustaceans and molluscs (and perhaps a seastar or two). And I really don’t know how plausible it is, but I’m pretty intent on finding out. I don’t know if anyone here has any experience with marine shrimp, but I figured I may as well see if any of the Aussies here are familiar with the shrimp I want to keep. So this species of shrimp is actually the species that got me into the hobby! I found them on a camping trip, and they were just so active and engaging, and I just fell in love. Then I went home, did a bunch of research, and got an aquarium. They’re part of the reason why I’m so interested in shrimp. Now I’m on holidays again (in a different place in Vic) and they’re everywhere in the tide pools. Millions. The species is ‘palaemon serenus’, the red-handed shrimp, and they grow to about 6cm for big females (which I discovered last night) and I think 3-4 for males. Just from observation. They live primarily in colonies of 10-30 under rocks during the day, venturing out when they feel safe, and going everywhere once it gets dark. They’re omnivorous, eating pretty much everything they can get their little claws on (including my fingers and toes). They look rather like freshwater macrobrachium, to be honest. I’ve had a look and it’s legal to collect from this location. There aren’t limits on anything I want to collect. So, I’m thinking I’d do a 20 litre tank for the meantime (until I can get some awesome 30ish litre low-boy tank). I’ve got one at home that could be set up as soon as I’m back. If I take home a big rock and sand, then I should have beneficial bacteria sorted, as well as a food source. The rock would have plants and a bit of algae and all the other good stuff you find on the rocks they like. Other than using salt for water changes, I’d run the tank like a freshwater tank - sponge filter for filtration, freshwater light, no heater, fortnightly or monthly water changes. I’d love to add a couple little fish if I can catch them, but I have no idea how to identify whether they’ll grow or not. Same deal with the majority of crabs (although I have ID’d a few species that would work). And unfortunately no nudibranch either… although I found the CUTEST little one last night. They’re apparently super specialist in terms of diet, and I don’t have the time to observe one for hours to see what it eats, ID it, work out how to cultivate it, and all that. So, that’s the plan. I would love any advice, recommendations, or criticisms you have. I understand there’s a good chance this could be too ambitious, and the well-being of the animals is number 1 priority, so if it sounds like it’s a bad idea then I’ll just scrap it. But I’m pretty keen on finding out a way to make this work.

      I have had fungus each time I set up a new tank, but it has always just disappered on its own after a month or two, and has been varied in appearance each time!

      Had a go searching / feeling throught the substrate for the tabs but no luck.  They might have dissolved or become soggy so I can't  feel them.  I have a bucket sample of substrate brewing at the moment for a 24 hour test and its already steadily rising the TDS.   Looks like a just wait and see...... Thanks for all the help as ususal it is appreciated.  Dirk
