Red Seaweed (Red Marine Algae)
Dried red algae sheets for grazing marine fish that need something to pick at all day, not just a flake at feeding time. Ocean Nutrition Red Seaweed clips into the tank on a feeding clip and lets tangs, angelfish and other herbivorous grazers browse naturally. It's a softer, spongier sheet than green nori-style seaweed, which suits fish with smaller or more delicate mouthparts. Available as an 8 g pack or a bulk 50-sheet pack for busy systems.
Key features
- Dried seaweed with garlic extract – a simple, two-ingredient sheet.
- Softer texture than green seaweed – suits smaller angelfish and fish with soft mouthparts.
- Clip-feed format – tear a piece to size and attach with a seaweed clip so fish graze at their own pace.
- Two pack sizes – an 8 g pack for occasional use, or 50 sheets for tanks that go through it regularly.

Which size do I need?
The 8 g pack suits a single tank being fed seaweed a few times a week. The 50-sheet pack is the better buy for multiple tanks, a heavily herbivorous stocking list, or a shop that goes through seaweed daily – it's the same sheet, just a lot more of it.
Suitable for, and not suitable for
Suitable for herbivorous and grazing marine fish – tangs, rabbitfish, large angelfish, pygmy angels, wrasses, damsels and some butterflyfish – plus many marine invertebrates and herbivorous freshwater fish.
Not a complete diet on its own for most fish – it's a grazing supplement best fed alongside a formulated flake, pellet or frozen food.
Ingredients
Dried seaweed, garlic extract.

Feeding directions

Common questions
What's the difference between the 8 g pack and the 50-sheet pack?
Same product, different quantity – the 8 g pack suits occasional feeding, the 50-sheet pack is the practical choice if you're feeding seaweed daily or across several tanks.
How do I attach the seaweed in the tank?
Tear a piece to roughly 5 cm by 7 cm for a 200 L tank and hold it in place with a seaweed clip. Reattach any piece that comes loose.
How long can I leave a sheet in the tank?
Remove any uneaten seaweed after 24 hours.
Will this work for a small angelfish with a delicate mouth?
Red seaweed is softer and spongier than green seaweed, which is why it's often preferred for pygmy and other small angelfish.
Can freshwater fish eat this too?
Yes – it's also suitable for herbivorous freshwater fish, not just marine species.
