In Stock

Optimal food source and Color Enhancer for Damselfish, small Angelfish, Sponge Feeders, and other Marine Fish with softer mouth parts. Red Marine algae is a nutritious supplement for all grazing fish, rich in vitamin C, and is 100% digestible.

FEEDING RECOMMENDATION: Tear off a piece of seaweed approximately 2 inches by 3 inches (for the average 55 gallon community tank) and place in the aquarium using any type of "lettuce clip" or attach seaweed to an aquarium rock using a rubber band or other practical technique. (Folding the seaweed piece prior to placement is also recommended.) Allow fish to graze at their leisure. Any large seaweed pieces that break loose and float to the surface should be reattached. Remove any uneaten seaweed after 2 hours.

NUTRITIONAL COMBINATIONS: This product should be used as a supplement to other food sources. We strongly recommend Formula Foods (Formula One, Formula Two, Brine Shrimp Plus, Spirulina Formula, etc.) and Aqua Yums (Bloodworms, Brine Shrimp, Squid, etc.) from Ocean Nutrition.

No, I would not recommend this.

Terrible Product

Pros: None

Cons: Breaks apart instantly as soon as it gets wet

I would give this product 0 stars if possible. While I use and love the green version of these sheets. This red version instantly breaks apart into small pieces as soon as you put it into the aquarium and it gets wet. This product made a huge mess in my aquarium and I spent the next several days siphoning the particles out and doing water changes.

Must be YUMMY!

Pros: Fish love it and it WILL be gone before it goes out of date!

After the fish get use to have a food clip in the tank they literally tear into these algae sheets! If you have tangs you have got to give this a try ... and most other fish seem to appreciate the "treat" as well!

My fish love this!

I feed this everyday and my tangs devour it as soon as i put in the water. Even my Maroon clownfish loves this and even tries to fight off my yellow tang from the seaweed clip. This stuff is great for all fish especially Tangs and any other herbivorous fish.
