I couldn't believe my eyes my I noticed something not quite right with one of my fishes, oscar. Sure enough, when i got a closer look I found out it was trying to swallow another fish- the shark! gosh, the poor shark fish was half way into the oscar's mouth, who had some difficulties to swallow it because the shark was quite big. I was afraid it's going to choke to death because from the time I first noticed that was at 7 pm and until the time I went to the bus station to send my mother, it's still there. Luckily when I came back oscar was done, because I've thought I might pull the shark out incase it still stuck in oscar's mouth.

look at this pictures from side. can you see the shark's tail coming out from its mouth?front view
