seaweed question
 

Hi there. I have 2 clowns and a regal tang. I'm wondering should i leave the piece of seaweed on the clip all the time so they can take as they want it or remove it in 2 hours?

no dont worry about it use the sea weed as food when its time

If you are using Ocean Nutrition Seaweed Select It tells you how long you should leave it in the tank. Green is good for 24hrs, if not eaten then remove.

Although many fish benefit from nori (seaweed), remember that the regal tang is a zooplankton eater so you should be feeding her meaty foods like mysis shrimp.
Other tangs are require algae.
