Siamese Fang Blenny (Meiacanthus smithi)
The Siamese Fang Blenny, Meiacanthus smithi, is a small, hardy and attractive marine blenny, recognised for its pale body, dark horizontal stripe and confident open-water swimming behaviour. Also known as the Siamese Blenny, Disco Blenny, Disco Fang Blenny or Smith’s Fang Blenny, this species belongs to the Meiacanthus group of fang blennies.

Jason Murray –
Added a Siamese Fang Blenny to my 120-gallon marine tank last month. It’s active and swims freely in the open water. The dark stripe stands out well against its pale body. Very peaceful and doesn’t bother other fish. Works well with live rock and other reef-safe species. Easy to maintain.
Boris Brown –
The blenny arrived healthy and has been swimming well in my tank for three months. It’s not aggressive and stays in the water column rather than hiding on rocks. Feeds well on planktonic food. Would recommend for reef tanks with stable conditions.

Great addition to my marine setup. The fish is active, colorful, and doesn’t stress other inhabitants. It’s easy to spot due to its distinct stripe. I’ve kept it with clownfish and gobies without any issues. Very satisfied with the purchase.
