These shrimp have 4 fanlike appendages which are used as filters for food. While most food is caught this way, the shrimp is able to pick up larger pieces. This shrimp prefers many hiding places, and enjoys a current to be able to feed in. Mine does not go very far from the tanks driftwood. This shrimp can be many different colors, from very pale light brown, to a dark red, though all have a white stripe down the middle of the back. For breeding; it does not appear to be much successful in the home aquarium, the larvae require increased salinity levels, and seem to have about the same needs as an Caridina japonica.

These shrimp are peaceful, fascinating creatures. Be careful when purchasing that you are definitely buying a fan shrimp and NOT a crayfish - the fan shrimp do not have pincers, but white fans. Be warned - they shed their skins every so often - mine does on average every 2 months - it looks like a little ghost shrimp in the water! They require good water quality with regular changes to keep nitrates in check. The ideal tank set-up for them is a mature, well-planted tank with plenty of hiding places. I currently keep my shrimp in a 400 L planted tank with a rainbowfish community. He never bothers anyone, and they don't bother him! Highly recommended addition to a community - although I would be wary keeping smaller specimens with large fish who might see them as a tasty snack.

Hmmm, bamboo shrimp, I had one of these when I was first starting out. These shrimp get a brilliant redish color and then fade off shedding their exoskeleton (quite often). They feed primarily by just standing in the water current and then wiping their fan appendages on their mouths. These are kind of creepy and live only about a year. If you want a more interesting setup these certainly get people's attention (mostly because people find shrimp ugly and bizarre).

Bamboo Shrimp are a very interesting species that add a lot of personality to a community tank. I have taken care of two bamboo shrimp, both in separate aquarium setups, with success. The first setup was a planted aquarium with 30 mollies. The mollies were interested in the shrimp, but were not aggressive toward it. I found it active at night, and pretending to be a plant during the day. The second time I decided to take care of a bamboo shrimp was when I was keeping a simple stacked rock low light aquarium with 10 guppies and 6 rasboras. Although stacked rocks are not the natural setting for these animals, I found it to be a neat, almost pseudo-cichlid design. The bamboo shrimp with the stacked rocks setup was much more active compared to the planted aquarium, which I believe is from having more dark hiding places. Not exactly a recreation of nature, but if there is room to stack 7 or 8 rocks on top of each other, it creates a nice place for bamboo shrimp to hide and feel safe.

These shrimp are very interesting and keep your water crystal clear. They turn bright red toward the end of their life. This is why they are also called a "flower shrimp." More commonly known as a "rock shrimp," they are very active. If they have plenty of food, they will leave your fish alone. They prefer sifting through the gravel and sitting in strong currents and filtering out particles of food floating in the water. They are a great way to add interest to a community tank. With their hard shells, they are even alright in an aggressive tank, after they reach adulthood. Also, if they are in an aggresive tank, they'll need a place to hide. I love watching my 5 cm, bright red, adult shrimp climb up on the rocks and filter the water for food.

These are facinating creatures and make any peaceful community tank more interesting. They are best kept in small communities, i.e., 3-6. They colonize on driftwood as a rule and like lots of places to hide. They are sensitive to overpopulation, i.e., too many active fish in not enough space. It stresses them out. Also high KH, high GH, high pH, and of course amonia/nitrates/nitrites. They should live 3-5 years when properly cared for. They are really interesting to watch at almost any time they choose to be active. Awsome addition if you are willing to do the work!
