My oscar fish is around 12 /14 months . Not sure what sex it is . But its gaurding a tube on the sponge filter like crazy . It looks like tiny little balls on it and allot of them . But they are all green like algae. The bigger oscar i had died about a month ago . He jumped out in the middle of night . I replaced it with a smaller oscar . The big one now is protecting that pipe like crazy . Do i need to remove and clean off that pipe . Its got air bubbles going thru it so dont know if they are really eggs or not any advice will help thank you
