Engineer (Neon) Goby – Pholidychtys luecotaenia

About this fish

Engineer (Neon) Goby – Pholidychtys luecotaenia is a saltwater goby for reef and fish-only marine aquariums. This species is known for “engineering” behavior—spending much of its time working through the substrate with its mouth and body, helping keep sand beds aerated and actively searched for food. In a practical sense, it’s a great choice when you want a living, interactive sand-dweller that also adapts well to a feeding routine and can be maintained alongside many peaceful tankmates.

Features:

• Active, substrate-focused goby that spends time sifting and foraging in sand
• Typically compatible with peaceful community setups when provided enough space and stable conditions
• Benefits from a sand bed where it can dig, hover, and search for food
• A good candidate for tanks with live rock and natural microfauna (supplements prepared foods)
• Usually does best with gentle filtration and aquarium flow that doesn’t blast the sand
