What is the safe fish to keep with Red Cherry Shrimp

Recommended Posts

Dimos

Hi everyone,

I was wondering what fish is safe to keep in the same tank with shrimp. I have a fish tank with tetras and a red tail shark. Lately the shark has been chasing the tetras a lot and they keep staying at the top, to avoid getting closer to the shark. Do you think it is ok to move the tetras in the shrimp tank? Attached is a photo of them, the are 1 inch each.

Thanks,

Dimos

The general rule of thumb is that if it's big enough to fit in their mouth it's going to get eaten. That said, I've kept my choc cherries with endlers without much issue in the past. They were breeding so much I probably didn't notice juvi's going missing. On the other hand, those same endlers chomped away at my sulas. AFAIK, the only shrimp safe fish is the otto.

I understand, in some cases having fish in the same tank is unavoidable. In those cases, you have do what you can to ensure the shrimp and the juvis have sufficient hiding places that the fish can't get in to. Looking at the size of those tetras, once they get the taste of shrimp, there won't be any going back.

I have White Clouds, Neon Tetras and Oto's in with my red cherries. Of course, some babies and eggs will get eaten, but the population steadily grows and I am always find babies / mid sized shrimp who have grown up in the tank. 

Other small fish may also work - ember tetras, mosquito/chili rasoboras, drawf rasbora etc. I have generally found that fish that do not grow more than 3cm tend to leave the adults alone - so thats my general rule of thumb without any scientific evidence!

As @NoGi rightly points out, no fish/shrimp combination is 100% safe or foolproof, however the smaller and/or timid the fish, the less chances there probably are for them to all be eaten. 

Providing plenty of plants and stones/wood for the shrimp to hide in and around always help.

Even fish under the 3cm range can be a danger, my Cherry Barbs do sometimes hunt the shrimp, which is kind of interesting behavior to observe but I wish they wouldn't. The shrimp are too big for the barbs to eat, but I'm pretty certain several of the smaller ones got taken shortly after they molted as the barbs tend to mob things once they figure out its edible. (I'm going to eventually make my current tank a shrimp only tank)

Then it looks like I have to find another place for my tetras, before they get eaten by the shark...

Yeah, or you could re-home the shark instead, they are notoriously aggressive and territorial fish and often won't tolerate others of their species (or conspecies) either.

 

Rehoming the shark seems like it'd be the easier solution anyway. How big is your tank again?

hmmm I also have a cichlid, which is the most peaceful cichlid you can get. Sometimes it chases the tetras, but not as much as the shark.

My tank is 20gallon and the shark is around 4 inches. Yes I heard you cannot have 2 red tail sharks in the same tank, it would be bad. So if I decide to rehome I will have to rehome both the shark and the cichlid, probably.

Well, that makes it easier, 20 gallons is too small for the shark, it's also too small for most any kind of cichlid that I know of, and definitely too small for the shark+cichlid+tetras all together.

But the rule of the thumb is 1 inch of fish per gallon of tank. So (given that my tetras are 1 inch each and the cichild 2 inches) I have:

4 + 2 + 5 * (1) = 11. I still have room for 9 inches of fish.

One inch of fish per gallon is a very outdated and poor metric for how much you can have in your tank. You need to take into consideration the fishes needs, not all fish are created equal when it comes to bio-load some are "messy" while others not so much, many fish need room to swim, being in too small a space is stressful.

 

Sharks for example need more than 20 gallons all by themselves, because they need room to cruise around, and they can grow up to 6 inches.

Yes, that's true! Recommended tank size for red tail sharks is bigger than 20 gallons. I guess I should be more careful on what fish to get next time... If you know someone with a pretty big tank that could take the shark please let me know. I live in the Boston area.

sorry, but based on My experience, I must suggest no fish for shrimp aquarium, We can not only think about is this fish will eat the shrimps ?

but I suggest We must think about other too, like will the shrimp not disturbing by fish waste/ammonia, fish activity, the fish maybe vegetarian but the shrimps maybe can not understand that, they will have fear and no joy in aquarium for the shrimps, but have some fish can be important, sometime We can send few fish to shrimps aquariums if the aquariums have too many other little bugs which disturb the shrimps colony, after the task finished, We must take the fish back to their own dedicated aquarium, I think it's more naturally :)

I'd like to chime in here. I've had very heavily planted tanks with fish up to 6-8cm in size with shrimps and the shrimps absolutely thrived..

However after a long period some fish must have discovered that shrimps were actuslly tasty snacks. Very soon all of the fish were munching on juveniles and babies and decimated hundreds of them!

Thanks Dimos and Revolutionhope.

I am understand that many shrimp keeper want to have a beauty aquarium with ornamental fish and shrimp swim together with peace, I know, cause I did it past ago ?.

But, as i stated above, please be patient and never thing again about that if Your purpose not just to have shrimp in aquarium, but want to have peacefull colony of shrimps, in my experience, even otocinclus, must be really veggie fish, can disturb the shrimps, even can make shrimplets "shocked" become shy, hiding along the days (maybe cause fear). For now, I even thinking why I keep fish like otocinclus to my shrimp colony only to eat algae, cause the shrimp is algae eaters too :(

if You want keeping shrimp with snails, I don't see much problem with it, as long as not too much snails.

attention, sorry for My English :D

Has anyone tried/kept spotted rasboras with shrimp?  They're fairly tiny.

hmm not sure, but I agree with the previous comments. It is better to separate shrimp from fish. Even if the fish is vegetarian, shrimp might feel nervous when having fish around. Plus, fish might eat some of the baby shrimp.

Thanks,

I wouldn't keep a slow breeding, pricey shrimp with fish, but if you're talking about Red Cherries...  Unless you have a good place to sell them, most people keeping them in good conditions will be overrun with Cherries eventually.  My cull cherries are multiplying surprisingly fast in the community tank with plenty of fish big enough to snack on babies.

      Hi ! 
      I live in Seattle where the water is incredibly soft and I have a tap water pH of 6.7, GH of 0-1 and KH 2. My existing tank with plants already has buffered substrate. Would I have better chance of keeping CRS than RCS with my current water parameters ? Or would RCS do okay?    I do have an RO system already, and I could  remineralize my water with salty shrimp KH/GH+. Which would allow my GH and KH parameter to be okay for neocaridinas, but I already have a tank with active substrate. I’m 100% I don’t have space to set up another tank with inert substrate.    Would do you recommend ? What are pH you have successfully kept neocaridinas and have them thriving ?    Thanks ! I appreciate all the help as I am new to the hobby.

      Help please!
      I bought a rack set up with 9 tanks and a sump. It is full of stock, neo-cardinia, cardinia  and sulawazi shrimps + a tank of endler guppys. 
      I am collecting it tomorrow with help from friends and a borrowed van. 
      Has anyone moved a rack before and what tips can they share please?
      We were thinking of lowering the water level right down and then moving them very gently in the cars - with the water in 25L drums in the van cause I don't have that much RO water spare so it will be going back in as soon as we can set it up. 
      They are moving less than 2km down the road and I will have my heating on full blast to keep the house warm - current temperature here is about 10 degrees celcius. 
      I am worried about the Sulawasis but I reckon if we keep them plugged in with the heater for as long as possible and put them back ASAP they "Should" be ok...fingers crossed. 
       
      I just read that tanks should never be moved with water in them but it will take HOURS to catch all the shrimp as there are literally hundreds of them

      Short info...

      I'm in USA
      I got these from a pet store
      They were being sold as something they clearly are not
      Larger than cherry shrimp, smaller than amanos (as in, at best, females get to the size of an adult male amano, but not female from what little I can see)
      *NOT* Neocaridina
      *LARVAL STAGE of 1+ weeks*

      I've been told these are 4 different species (well, 6 or 7 if we count the ones I know aren't true) so I'm looking for some second opinions on what they might be... what I do know is that after a week or so, the larvae have not transformed into miniature adults. These are some of the more colorful shrimp, some have less colors but they all mainly share the dark "band" midway down their tail, except males which may appear very bland. (I'm not entirely sure it's only one species of shrimp...)
       
      Female
       

      Male
       

       
      And a 5+ day old larvae/zoe (younger zoe don't show as much color - more clear)

       
       
       
       
      And just to throw a curve ball in there... here's another shrimp that was mixed in with the type above! (clear shrimp, appears more yellow than he really is... this is also a relatively small shrimp, hardly any bigger than an adult cherry shrimp. He's the only one...)

      So I currently have a 6 gallon planted tank that has been set up and running for 3 weeks. Im about to purchase my red cherry shrimp to put in this tank. There is plenty of algae in the tank for them to eat, so food should be fine for the beginning correct? Plus it is heavily planted meaning there is plenty of organic matter to be consumed at all times, so they shouldn't really need to be fed ever? Also i see that drip acclimation is best for getting them used to there new home. If i did this till the tank is half empty for provided them with as close conditions as possible without emptying the tank. Am i good to just refill the tank afterward or from now on when i do water changes do they all need to be dripped in? Also is it true that adding calcium to the tank is beneficial for the shrimp to molt?
      Im a pretty experienced fish keeper, just haven't ever had with shrimp so I dont want to kill all these expensive shrimps due to lack on knowledge. Any more knowledge or advice that can be given to me is high encouraged, even if it seems simple. 
      Some specs of the tank, tanks does have a filter, that has small openings that could suck up baby shrimp. Its a small filter and has algae growth on the openings so it really does reduce the flow a bit, where i dont see it becoming a  huge issue. The tank is co2 injected, but thats pretty nailed down so nuking them with co2 is highly unlikely. The tank has a soil bottom capped with coarse sand. The vast majority of the bottom of the tank is carpeted with plants but they still have a way to go. There is no lid on the top of the tank. The tank does have some natural river stones in it with the brown algae growth on them. And a lot of the plants have the white "bugger" algae growing on them or around them. The tank receives about 10 hours of light a day. I know i put a lot of un-important information here, but maybe a pro will see a problem here and be able to inform me so I can correct it. Thanks for your time and consideration in advance!!!!
      Regards
      -The Keeper

      Traps don't work on hydra. Even with planaria, it is slow and it doesn't catch them all.

      Very wise as once they start breeding your population may sky rocket anyway, as they have with the CBS! I'm sure you should get some really nice surprises/colours when they start cross breeding too! Simon

      I will stick with the present shrimps, give it another month or so before I add some more shrimps.

      More fantastic pictures love the blue shadow panda and the 2 red pinto galaxy. Great to hear all is going so well! If you have a lot of CBS then they will breed when they are old enough so losing the 'mother' isn't too bad at this stage and they only love max 2 years anyway. Glad you still have 2 blue bolts as well - those will probably be my next purchase when they are in stock? The putting spinach in my tank has brought a few of my shrimps out but bizarrely they aren't touching the actual spinach? Seen 2 black and 3 red (of the 8 total I bought) so far today? Simon

      update my new tank is becoming stable, the shrinps are growing, I have seen many of the shrimps shread it's shell.   My old tank is infested with black CRS, but the mother had just died yesterday, I still have two blue bolts and a few CRS.
