I'm guessing this is a chemistry question -
I have a 5g that I use to Q new arrivals. Right now it has some gold ramshorn snails that I'm growing out and a colony of ghost shrimp. I sometimes put cuttings of plants in there for the snails. REcently I q'd 6 juvenile rainbow fish for 3 weeks. I fed them pretty heavily on frozen bs and bloodworms. Now when I vacuum or stir the gravel by planting a plant, I get bubbles that rise from the substrate, which is about 1.5 inches of gravel. What are the bubbles? Is there some sort of anaerobic action going on?
