I have a question...
My Fish Tank has a ton of bubbles lining the top, and it goes around the tank ,plus the bubbles go up to about three inches. Also I see a filmy(ish) oil on the top of the water.
I clean my fish tank once a week, and I scrub all the scum off the bowl. I just want to know what the bubbles are since they don't really pop.
My mom said I feed my fish to much, but I feed three flakes three times a week.
Please help me know if I should be concerned about these.
