This spicies might be a threat to smaller fishes.
This species thrives best in an aquarium with dimmed lighting.
This species can be a threat towards small crustaceans, e.g. small shrimp.
This species must be fed with an appropriately varied diet.
This species is nocturnal and therefore the most active when the light is dimmed or turned off.
The Snapping-/Pistol shrimp derives its name from the snapping sound their large claw makes, which can paralyze their prey. One will therefore often hear clicking sounds coming from the aquarium.
Apart from small shrimp, they are not normally a threat to other creatures in the tank.
Their needs and colour do vary, but common to most of them is that they will generally thrive best as a symbiotic pair with one of the following species: Amblyeleotris spp., Cryptocentrus spp. or Stonogobiops spp.
It is important to research beforehand which fish and shrimp go well together, to avoid the risk of the animals not wanting to pair up.
As a symbiotic pair will make a shared cave in the sand it's important to have a deep enough sandy substrate.
Snapping-/Pistol shrimps can be fed with small pieces of seafood or larger types of frozen food.
Shrimps have many different purposes in the tank, some are just pretty while others are shy but useful. Some remove parasites whilst others help fight different pests.

Minimum volume
"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
Hardiness
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
Suitable for aquarium
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Reef safe
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
