recently I found one of my shrimps eating at another, I have since isolated the injured one and upped the amount of food being given to them. what should i do with the injured RCS? how long will it take to heal?

Thats a new one on me, I have seen them eat dead ones but never a live one! Be careful not to overfeed as a reaction as that could put them all at risk? I don't think they heal as such like some crabs that grow back, if it is badly injured it may be better to euthonize it!

Not true. Shrimps that have lost all their legs can grow them back.

Keep them safe from being attacked again. Separate it. Get a breeder cage, those are great for holding sick shrimp too.

It depends on where the shrimp is injured.

As I said above, legs and antennae can grow back.

 

Try feeding your shrimps frozen blood worms, that you can get at any aquarium. Sounds like your shrimp need some protein in the form of meat.

I didn't realise they grew legs back like some crabs can, good to learn something new.

I am reading the 'invertebrates' book at the moment and lots of crayfish seem to eat each other if they don't get enough protein as JayC states!

shes injured between the the carapace and the abdomen, I've separated the shrimp and shes looking a bit better, a breeder cage is a good idea 

can I get some recommendations on food? i have been feeding them a bottom feeder pellet recommended to me  by another shrimp keeper that is high in protein but my shrimp just don't seem that interested and would rather scavenge.

thanks for your help!

that would have been my first instinct, let nature take its course and all that, but shes one of my favorites so I'm willing to go a little further for her

what foods would you recommend? i have high protein bottom feeder pellet I've been feeding them but they don't seem that interested in it 

thanks for your help

Shrimp king make a food Protein and as JayC says bloodworm. I use the tetra bloodworm in a tube for my betta if you don't want frozen, though depending where you are it may not be available in your country.

Is this a newly set up tank as mine don't touch food yet but just graze as there must be enough biofilm to keep them happy in the tank that is 3 months set up.

it is a new tank yeah, less than 2 months old (not including cycling)

You sound the same as me as my 3 months included a month cycling so shrimp have been in the tank 2 months also. At the moment they won't touch any food, or cooked vegetables and I assume it is because there is enough biofilm to keep the (maybe) 10 shrimp fed. Adding another 10 shrimps today so that may change if there isn't enough for them all but I will have to wait and see?

i went from 10 to around 20 the other day due to a gift from a friend and haven't noticed any change in the feeding habits, most were juveniles/shrimplets though so wait and see i guess

What size aquarium is it and what type of shrimp are you keeping in it?

Simon

sorry I realised you said RCS. What sort of setup have you got?

I've had a shrimp eaten alive when I started keeping shrimps back in November, it was eaten in the stomach, the chances of it surviving is slim, so I wouldn't waste time doing anything.

its a 5 gal that's been heavily planted, here's a photo https://drive.google.com/file/d/1LrXAm09zZeSGdshppbzUXjIb-kyd4jLS/view?usp=sharing 

the one that's been injured is closer to a fire red than a RCS but the rest are low/mid grade 

yourself?

Your tank looks great and very well laid out, shrimps will love it in there. It is similar size to mine so it is interesting that IF you cycled for a month and then added shrimp we both have the same happening. Probably the biofilm/algae in that size tank should be enough for 10 shrimps and it would have built up whilst the tank was empty of shrimps in the cycle period! 

My tank is soil substrate with bee shrimps and lots of hideous algae but I am hoping that will clear itself. I haven't had that problem before?

If you are going shopping for food, I would also get some 'baby' food as well for when you get newborns, it is usually a powder and I use the chi ebi. I think most people (me included) don't clean the back (or sides) of the glass inside the tank as that biofilm is good for the shrimps (especially babies) to eat, though it doesn't look very attractive? Always feed a lot less than the manufacturers recommend as overfeeding will kill shrimps and is probably the most common problem.

Hope the injured one recovers!

Shrimp that are new to the tank will be slow in accepting processed foods especially when there is biofilm available. They will eventually learn to eat pellets when they get hungry. But don't wait in getting the bloodworms however. 

Note: Protein you  find in pellets foods is never going to be as good as the protein from meaty products like bloodworms. (Don't feed them steak though, LOL). Drop a pinch of bloodworms into the tank and watch them fight for it. Bloodworms are especially good for shrimp before they moult and breed. The female shrimps need the protein much more and their chances of a recovery is much faster after moulting/breeding/laying eggs.

Don't be too hung up on only feeding pellets and bought foods. The occasional kitchen vege scraps can be washed, blanched and fed to shrimps too. Look around your garden for leaves and flowers. Mulberry leaves are a favourite of shrimps. If you don't have a mulberry near by, look for Oak leaves that have dropped for Autumn. Flowers like roses, hibiscus, dandelions, nasturtiums, and almost any flower can be fed fresh by just dropping it in the tank as long as you know no pesticides have been sprayed on it. I'll bet you these veges, flowers and leaves have more nutrition than processed foods. The added bonus, flowers for example, have antibacterial and antifungal properties. And flowers have an abundance of vitamins and minerals, flowers also contain a huge amounts of carotenoids and flavonoids compared to leaves. Specifically, Crytoxanthin, Zeaxanthin and Lutein which is obviously lacking in the leaves. These carotenoids enhance the colour of shrimps. 

Have a read of the food & nutrition forum for a lot more ideas on foods you can use. https://skfaquatics.com/forum/forums/forum/44-food-nutrition/

@sam, if you add in your location in your profile, we might be able to give you better advise on foods based on your location.

I'm from Perth and there's a mulberry tree around the corner, do the leaves need to be dried first or are they best put in fresh?

I will try bloodworm myself today, it never occurred to me for shrimps, but I have it for the betta.

Try and always use leaves or other food that has no pesticides or pollution on it as that could kill the shrimps.

With mulberry leaves, either method is just as good.

Dried leaves last longer and can be left in the tank. Fresh leaves have higher nutrition.

So alternate the two. With fresh leaves you can drop them in fresh, but the shrimp won't eat them until it goes soft. So it's great for feeding when you go on holiday. Or you can blanch the fresh leaf and drop it into the tank, the shrimps will eat that sooner. Dried leaves are also good for when you go away.

It's on my shrimps staple diet for a while now. You should try it.Don't put too much in however, just enough for one per shrimp.

Dried, frozen, or live bloodworms? I should pick some up.

Probably best to just put a small amount of the bloodworm in first and see if the shrimp eat it otherwise it will pollute the water too much! My shrimp wandered passed it but weren't interested but the snails seem to be feasting on it so it wasn't a waste.

Frozen bloodworms.

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony. 
    • sdlTBfanUK
      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
