Hi everyone. New guy here from the Philippines. I just have a question on feeding my new saltwater fish. My mom bought me a new tank plus 2 threadfin butterfly fish. In our backyard, we have a fish pond. There are some old corrals there that have grown moss on them. Is it suitable for me to put said corral in aquarium? I read online that they like to graze on algae. Is the moss considered algae? If so, how should I clean it? Boil, dip in hydrogen peroxide etc. i am wondering about this because the nearest pet store that sell algae wafers and such is 4 hour drive away. I cannot regularly go there to get food. Any help appreciated! Please pardon my english.
