Seaweed-Eating Saltwater Fish

In saltwater aquariums, seaweed and macroalgae are essential food sources. Many herbivorous fish, such as tangs and rabbitfish, depend on seaweed for daily nutrition, while omnivores like angelfish and clownfish use it as a healthy supplement. Offering live seaweed (Ulva, Gracilaria, Chaetomorpha, etc.) keeps your fish healthy, colorful, and active — and helps prevent them from grazing on corals.

1. Tangs & Surgeonfish (Acanthuridae)

Examples: Yellow Tang, Blue Tang, Kole Tang, Sailfin Tang
Among the most enthusiastic seaweed grazers

2. Rabbitfish (Siganidae)

Examples: Foxface Rabbitfish and related species
Constant grazers, thrive on live macroalgae in the tank

3. Angelfish (Pomacanthidae)

Examples: Regal, Queen, Emperor, Flame, Coral Beauty
Omnivorous — eat seaweed along with sponges and meaty foods

4. Blennies (Blenniidae)

Examples: Lawnmower Blenny, Tailspot Blenny, Bicolor Blenny
Specialized algae grazers that benefit from live seaweed growth in the tank

5. Wrasses (some species)

Most are carnivorous, but Halichoeres wrasses and a few others nibble on seaweed occasionally

6. Damselfish & Clownfish

Omnivores that sometimes eat seaweed or pick at live algae

7. Butterflyfish (some species)

A few species will eat seaweed in captivity, but most prefer corals and invertebrates

8. Herbivorous Gobies

Certain species graze live algae regularly, especially in tanks with natural macroalgae growth

Fish Group	Role of Seaweed	Notes
Tangs & Surgeonfish	Primary food source	Need constant access to live macroalgae
Rabbitfish	Primary food source	Strong grazers, thrive with live seaweed
Blennies	Primary food source	Especially lawnmower and algae blennies
Angelfish	Supplemental	Combine with sponges and meaty foods
Wrasses (some)	Supplemental	Only certain species eat it occasionally
Damselfish & Clownfish	Supplemental	Opportunistic grazers, not reliant on it
Butterflyfish (some)	Supplemental/rare	Most prefer corals/invertebrates
Herbivorous Gobies	Supplemental/primary	Varies by species; some graze constantly

Grow live macroalgae (Ulva, Gracilaria, Caulerpa, Chaetomorpha) in a refugium or directly in the display tank
Provide a mix of red, green, and brown live seaweeds for balanced nutrition
Anchor live seaweed to rocks or substrate so fish can graze naturally
Maintain strong lighting and good water flow to keep macroalgae healthy

Live seaweed not only feeds your fish but also improves water quality by absorbing excess nutrients, helping reduce algae blooms and keeping your reef tank balanced.

Freshwater Fish That Eat Seaweed

While seaweed is mostly used in saltwater tanks, many freshwater fish benefit from algae, spirulina, and plant-based foods. Some rely on it as a primary food source, while others eat it as a supplement.
