Flagtail Shrimp Goby
(Amblyeleotris yanoi)

Description

The research provided good information on *Amblyeleotris yanoi*.
Here’s a summary of the gathered data:

* **Common Name:** Flagtail Shrimp Goby (also Flagtail Prawn Goby, Yanoi Goby)
* **Appearance:** Elongated, slender body, whitish coloration with five diffuse bands of light orange-brown. Dorsal side has brown saddle-shaped markings. Caudal fin is yellow with a red-orange central area and oblique blue bands. Pelvic fins are connected by a membrane.
* **Behavior:** Territorial, can be aggressive towards its own species. Shy, especially in new surroundings. Bottom dweller. Known for symbiotic relationship with Alpheus Snapping Shrimp (e.g., *Alpheus randalli*), where the goby acts as a lookout while the shrimp digs and maintains a burrow. Good jumpers; requires a tight-fitting lid.
* **Care Level:** Moderate, sometimes listed as Easy. “Suitable with care”. Advanced aquarists.
* **Temperament:** Peaceful, but territorial towards own species.
* **Compatibility:** Can live well with other peaceful reef fish (clownfish, surgeonfish, small gobies). Should not be kept with aggressive or fin-nipping species. Reef safe, but potential threat to small, delicate ornamental shrimp (other than its symbiotic partner).
* **Tank Size:** Minimum 100 L (26 gal), 30 gallons (~113 L). Recommended larger (200L) for multiple specimens. Low aquarium with more horizontal surface area is preferable.
* **Water Parameters:**
* **Temperature:** 27-29°C (80.6-84.2°F). Some sources 22-27°C (72-82°F). 72-78°F (~22-25.5°C). Will use the consensus range of 22-29°C.
* **pH:** 8.0-8.5. 8.1-8.4. Will use 8.0-8.5.
* **Salinity/SG:** 1.020-1.026. 1.020-1.025. Will use 1.020-1.026.
* **Alkalinity:** 8-12 dKH. (Will omit dKH as it’s not a required parameter in the template, but good to note for context).
* **Substrate:** Deep sand bed for burrowing, sand, coral pieces, shells, small rubble.
* **Diet:** Carnivore. Feeds on small crustaceans (krill, mysis, artemia), flake food, frozen food. Finely chopped fresh or frozen meaty foods (krill, marine fish flesh, mysis shrimp, shrimp, scallops, squid, clams). Small sinking enriched shrimp pellets. Can scavenge for natural food in sand. Needs frequent feeding, especially when new. Some algae-containing foods can be included.
* **Maximum Size:** 13 cm (5.1 inches). Some sources 5 inches. One source mentions 13 cm for males, 5 cm for females. Another 3 inches (~7.6 cm), another 6 cm, another 3.5 inches (~8.9 cm), another 4 inches (~10 cm). I will stick with the most commonly cited maximum of 13 cm.
* **Origin:** Western Pacific Ocean, from Ryukyu Islands to Papua New Guinea. Indo-Pacific. Australia, Indonesia, Central/West Pacific. Southern Japan, Bali, Flores (Indonesia), Palau. Wild caught.
* **Lifespan:** Several years. Specific number not consistently provided. Will state “Several years”.
* **Swimming Zone:** Bottom dweller. Spends time at burrow entrance.

Conflicting data points:
* **Max Size:** Ranges from 3 inches to 13 cm. The 13 cm is consistently cited by multiple sources. I’ll use 13 cm. The female vs. male size difference from Wikipedia is interesting, but other sources just give a single max size. I’ll use the overall max size.
* **Temperature:** 27-29°C vs. 22-27°C vs. 22-25.5°C. I will choose the broadest range that covers the consensus: 22-29°C.
* **Care Level:** Moderate vs. Easy vs. Advanced. Given the need for specific substrate, symbiotic partner consideration, territoriality towards conspecifics, and jumping tendency, “Moderate” seems most appropriate for responsible fishkeeping. “Suitable with care” also leans towards moderate.
