Lol the Oscars and bass all look like they are hatching revenge plans against ya. Kind of reminds me of an old pet largemouth bass my dad had, always looked like he was upto something which we found out he was. Apparently he had a thing against my dad's cat "Buddy" and bit his tail when he was drinking from the fish tank. The second time he got him good, ever heard of the phrase "cat got your tongue"? Well the bass flipped the script on that and grabbed the cats tongue instead lol. Least to say the cat never drank from the fish tank ever again.
