- It is important to NOT overfeed, as any excess nori that is uneaten may contribute to the lessening of the water quality in the aquarium.
- Only feed what the tank inhabitants will consume in a short period of time, removing any excess nori that may be floating around in the water or that settles on the bottom of the tank uneaten after an hour or so.
- To enhance its nutritional value, you can option to apply a few drops of a liquid vitamin supplement such as Selcon onto the dried nori and allow it to soak in before feeding.
- Any unused nori should always be kept dry and stored in an airtight container! It WILL absorb moisture from the air, which particularly in high humidity regions may cause it to become damp and grow mold on it, making it unusable.
Something to remember when you first start to feed your fish and other tank inhabitants nori is that often they are afraid of it to begin with, because they are not used to seeing something strange drifting or waving around in their tank. They may avoid it until they get used to seeing it and figure out that it is food.
- If using nori in the full sheet form you can:
- Cut or tear off a long strip or chunk of the nori, roll it into a tube shape to help prevent rapid disintegration, then secure it into a veggie or feeding clip and stick it into the tank, positioning it in a low current area.
- Depending on what type of fish and other inhabitants you are feeding, the clip may be placed either mid-way in the tank, or near the bottom so bottom-dwelling animals like algae eating hermits and crabs can get to it. You may even consider using two clips if you keep both types of tank inhabitants, so they do not have to compete for the same food source.
- Cut or tear off a long strip or chunk of the nori, roll it into a tube shape to help prevent rapid disintegration, and using a good heavy live or other type of rock or decorative item in the tank, sink and secure the nori on the bottom by sticking a small portion of it underneath the anchoring item. Once the exposed portion of nori has been consumed, lift up the anchor and either let the piece underneath float free in the water, or remove it.
- Tear or cut off a few small pieces or the nori, hold it in the tank water rubbing it between your fingers lightly to re-hydrate it just enough to soften it up, then release it into the water.
- Chop or cut it up and mix it into any type of homemade fish food recipe.
- If using prepackaged types of nori you can:
- Just follow the feeding instructions on the package.
- Add and mix it into any type of homemade fish food recipe.
As a few final notes, in Robert Fenner's FAQs on Foods/Feeding/Nutrition 1 (refer to the "Seaweed For Food" topic), he suggests looking for other types of algae for human consumption like kombu and karame(?), which he states can also be found in grocery store oriental food departments. Even though nori is very inexpensive and can be messy to deal with, more expensive fares like Seaweed Salads, Selects, Julian Sprung's Sea Veggies and other brands of manufactured algae or seaweed based foods can be purchased readily at fish stores.
