So basically my problem is that some of my cat's hair got into my fish tank, dont know how. After I noticed it, I quickly vacuumed it trying to take out some of the hair, but I wasn't able to get all of it, there is still some lint floating around in the tank. My question is, should I be worried? My fish do seem fine, acting like usual, I might just overreacting but I don't want anything to happen to my little guys. Just trying to make sure. Any help would be great. Thnx in advance.
