Red Cherry Shrimp are an easy invertebrate to keep, even for a beginner. They produce a minimal bioload, and stay quite small. Being a peaceful species, they should not be kept with larger, more aggressive fish. Suitable tankmates include guppies, snails, and other slow-moving peaceful fish. Although some people have success keeping them with bettas, I do not recommend it, because shrimp can be very tempting to a hungry or aggressive betta. Their preferred environment is an aquarium filled with dense plants, such as Java Moss, containing a Nitrate level of 5 ppm or lower. Filtration for a cherry shrimp tank should either be an air-driven box filter, or an adjustable-flow power filter. I find that covering a power filter's input with panty-hose is an effective way of keeping the shrimp and their offspring out of it.

This is a very fun species to watch graze in an algae-filled aquarium. Not only do they effectively clean algae in aquariums, but they also clean up any excess fish food on the bottom of a tank. Red Cherry Shrimp are also plant-safe, making them an excellent addition to a planted tank for a cleanup crew. Another important part of their diet is micro-organisms that are found in mature aquariums. If you want to boost the population of these micro-organisms for extra food in your cherry shrimp tank, you can add dried oak leaves as a colonization area. You can also squeeze the "dirty" filter media into the aquarium, for your shrimp to feed on.

Breeding is very simple. Keep the water very clean, at about 27C, with lots of plants and hard water, and you are sure to have a tank teeming with the little guys in no time at all. To sex them, just look at their body colour when they are sexually mature. Females will have the intense red colour that cherry shrimp are known for. Males will have a more bland, occasionally clear appearance. Some females also have visible ovaries. They look like a big yellow/white spot behind the front portion of their body.

Shrimp keeping is a quickly growing hobby, but is not as popular as keeping fish in most areas of the world. If shrimp are not available in any pet stores in your area, try to contact a local aquarium club. Most quality shrimp that are available come from private or hobby breeders.

Yeah, females really a stand-out red, last time I kept around 10 adult size and 10 juvenile size. After around half a year I lost count of them, since too many were hiding in my tank. It's really hardy and easy to keep. The females are like auto-breeding machines. Nothing needs to be done to get them pregnant or anything to prepare them. Really recommended to keep, even for beginners.

Cherry Red Shrimp are very hardy and an easy freshwater shrimp to breed. Mainly needed is a tank, minimal would be a 40 L if wanting to breed around 100+ of them, heater around 25C, a filtration system with either a filter bag or a sponge covering the filter intake. Also some plants for the shrimp to hang onto. Should be fed veggies such as peas, and food containing mainly vegetable content. I have a 40 L tank in my bathroom, and bought 15 from an online auction. About 4 died by jumping out of the tank or happened to die off. But up till now, I have had 4 successful birthings and have now 4 generations of cherry red shrimp. Plus I have a few berried females right now. Cherry Red Shrimp are really a basic shrimp to breed and take care of. My tank in my bathroom is a cherry red species tank with a few amano shrimp and no fish. I basically breed them from the 40 L and disperse them to my 110 L or 20 L. Best to buy Cherry Red Shrimp around the juvenile staged and not up to adult sized, because they adapt better to the water as well as there surroundings.

I obtained six red cherry shrimp from my local pet store. Three of them are females. After two months of having them, I got 30 shrimplets crawling around my tank. Very easy to breed, just add water and Java moss then let them do their thing.

Red cherry shrimp are really small and easily preyed. I have about five of these and they do a very good cleaning up of the tank that I have. Most of the fishes, even the shy ones, can sometimes be rather aggressive towards these shrimp because of their brighter coloration and small sizes.

Cherry shrimp are pretty hardy and easy to keep. I've had a few lie motionless on their side for quite some time. This is normal behavior, as they are simply preparing to molt (one may not come across this often as they usually find a nice place to hide first). You'll know if they pass away because their bodies will turn opaque (sort of like how the shrimp we eat turns white when cooked).

It might also be useful to mention that these shrimp are a high order shrimp, meaning that their young emerge as fully developed, miniature versions of the adults (as opposed to low order shrimp, such as the ghost or glass shrimp, which go through a larval phase after hatching). This makes them exceptionally easy to breed, as no special care is required for the young, except maybe for some more frequent water changes to keep them at their most comfortable.

Mine are fed mainly on Hikari Crab Cuisine, and will happily accept most blanched vegetables (peas with the skin removed, spinach in particular), but interestingly don't show much of an interest in blanched carrots. That may just be a quirk, but I haven't bothered to investigate further. They are constantly grooming the glass, plants, decorations, and my sponge filter for a quick meal. I'm never concerned about overfeeding or underfeeding with these guys.

They are great at hiding-- I wouldn't be all too concerned about keeping them in community tanks as long as it is heavily planted, but obviously they are tiny and would be delicious to nearly any fish with a big enough mouth. The young in particular are vulnerable to even the smaller fish species, such as tetras. So if you are interested in breeding (or even just seeing them more often), they are best kept on their own.
