Amblyeleotris wheeleri Breeding Guide

Amblyeleotris wheeleri is a widespread Indo-Pacific shrimp goby that pairs with the alpheid Alpheus ochrostriatus in a shared burrow. This guide covers pairing, the burrow setup and the limited published data on its spawning and larvae.

Overview

Amblyeleotris wheeleri (Polunin & Lubbock, 1977) is a reef-associated goby of the Indo-Pacific, ranging from East Africa to Fiji, north to southern Japan and south to the Great Barrier Reef (FishBase). It reaches about 10.0 cm standard length and is found in rubble areas near or within coral reefs, on coastal sand slopes and in deep lagoons, usually at 5 to 15 m, in symbiotic association with alpheid shrimps, most often Alpheus ochrostriatus.

Sexing

FishBase lists no maturity or external sexing data for this species. As an Amblyeleotris shrimp goby it forms monogamous pairs, so sex is inferred from a settled pairing rather than fixed markings: two compatible fish holding one burrow without sustained aggression are treated as a pair.

Conditioning

Conditioning relies on stable reef parameters and frequent feeding. As a carnivore, the goby takes small meaty foods such as enriched mysis, brine shrimp and finely chopped marine items roughly twice daily. A securely paired Alpheus shrimp lowers stress and keeps the fish feeding near the burrow rather than hiding.

Breeding Setup

A breeding-oriented system reproduces the rubble-and-sand-slope biotope with a deep sand bed and rubble the shrimp can build into a tunnel. Pairing with a compatible Alpheus shrimp such as A. ochrostriatus is central: the shrimp excavates and maintains the burrow while the goby acts as a lookout, the shrimp keeping near-constant antenna contact with the fish (Amblyeleotris, Wikipedia).

Spawning Behavior & Trigger

Amblyeleotris gobies form monogamous pairs and lay demersal eggs inside the burrow, which the male guards until hatching (genus account). Species-specific clutch size and exact triggers for A. wheeleri are not given in the cited references and are omitted; a stable, well-fed pair with a settled shrimp partner is the practical prerequisite.

Egg & Fry Care

The male tends the demersal eggs in the burrow until they hatch, after which the larvae are planktonic (genus account). Raising these planktonic larvae requires a separate rearing tank with appropriate very small first foods and stable conditions; a detailed protocol for A. wheeleri is not published in the cited sources.

Common Challenges

Successful home breeding of Amblyeleotris is rare because the delicate eggs and small planktonic larvae demand specialised care. The larval phase is the bottleneck rather than pairing or settling, and a tight lid is advisable since shrimp gobies readily jump from open tanks.
