A strange fish.

I had this dream last night where I was in a fish store looking at a tank with some fish inside it. But one fish was really strange, and quite different. A yellow fish, with a face that was unlike any fish I've seen. With forward facing eyes, that were merely just circular, white and with pinpoint black eyes that protruded outwards from stalk-like protrusions from its head. In addition, this fish was incredibly aggressive. It would swim around to the other fish in the tank, casually taking chunks out of them, and I recall seeing a still living fish with its pink flesh and spine visible. It would go to all the other fish and completely rip them to shreds. This fish would do this to every single fish inside the tank. At the end, it then noticed a fish that was buried in the sand, some kind of flat fish, and it would try escaping into the sand. But this carnivorous aggressive fish would use its fins to dig it from the sand before completely ripping it apart. After it was lone, the dream just shifted my view to a different tank which was dry. Except, the same fish would be in this dry tank but it had bulbous proportions. There were two of them in this tank. The adjacent tank from before, now had a different appearing fish sort of like an Oscar. I remember I looked up the name of this fish, but I cannot remember what it was called. The dream ended shortly after I had witnessed these events.
