Likely Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Indo-West Pacific Ocean
Size: 2 inches (5.5 cm)
Natural Environment: Inhabits rubble bottom areas living in caves/burrows with various goby species.
General Husbandry: Rarely available in the home aquarium trade.
Once in the aquarium, rarely seen, yet usually heard at night by snapping the fingers of its single, yet exceptionally large claw. Loud enough to awake light sleeping aquarists.
Best maintained in reef aquariums with hiding places or fish-only aquariums with lots of live rock for protection and possibly a host goby.
As to diet, late evening snacks of meaty foods, e.g., small strips of fresh fish/shrimp flesh, sinking shrimp pellets or meaty freeze-dried foods placed near the area where it hides during the daytime will help reduce the nose it makes at night while hunting and/or provide some of its nutritional needs.
May eat small shrimp, snails and tubeworms.
May attack ornamental shrimp.
According to aquarist John Gibbin in the UK, his Cryptocentrus cinctus and Stonogobiops nematodes gobies both partner with Alpheus bellulus.
Experience Level: Intermediate
Aquarium Environment: Reef or fish-only aquarium
Coral Safe: Yes
Fish Safe: Yes
Invertebrate Safe: With caution
Acclimation Time: Shrimp are 'very' sensitive to specific gravity/salinity changes. Therefore, be sure to adjust the bag's water to that of the aquarium in which it will be placed by slowly adding small amounts of aquarium water to the bag every few minutes. In most cases, this process should take at least 15 minutes.
Aquarium Hardiness: Moderately hardy
Calcium (Ca): 380 - 430 mg/l
Alkalinity: 2.5 - 3.0 meq/l
Phosphate (PO4): <0.05 mg/l
Magnesium (Mg): approx. 1350 mg/l (relate to specific gravity) Extremely important for molting!
Strontium (Sr) 8 - 10 mg/l
Iodine (I) Trace element additives containing iodine should be used as recommended by their makers, as iodine is also vital for the molting process.
