Well i may be off on my guestimate of the size of the cat because he cant even fit the 4" red devil i tossed in there in his mouth but he is growing fast. My pool isnt inflatable not the walls anyway so he wont be chewing a whole in it before they go in the 1000 gallon tank im building in a different room in the basement. The concrete under the pool is sucking too much heat from it. Maybe the little 8" pacu did nip the big aro and make him jump, who knows lots of maybes. Ive had lots of pacu in my time and never seen them nip anything ever so who knows. Different fish do different things. Maybe the little dovii would kill a big peacock bass, lots of maybes, lots of opinions and ive never seen anything from any of my fish that you say youve seen. Even when i was video taping the pool to see the oscars spawn i didnt see any of what you have seen, who knows again lots of maybes. Maybe your fish you watched were cramped in a little itty bitty space, who knows lots of maybes. lol
ya know what i mean
lots of maybes
at least youve made my day enjoyable and slightly amusing
