Question shark problem

we recently bought 2 sharks and one of them is behaving strangely. not sure what kind of shark it is. it looks like a columbian but with stripes. it hasn't eaten since yesterday, and just floats in the corner, or it would "stand" by the wall as in the 2nd picture. don't know if it's sick or what. the other fish (danios and a goldfish) are doing fine. help?

Need some more info, how old is this tank? How long have you had the fish? How large? Off the top of my head, it sounds like ammonia poisoning. Goldfish should NOT be in the same tank with these "sharks", the sharks are tropical fish and goldfish are coldwater fish, they have different needs. Take a look at the link in my signature below for some more info.

5-gallon tank, 2 weeks old. got the sharks a few days after the tank.

this shark died, the other shark is doing fine.

My best guess would be that its hasnt had the time to fully cycle. Ammonia and Nitrite culprits much?

Oh dear, your tank is WAY too small for even one of the fish I see in there. Your fish died of severe ammonia poisoning and your other fish are next, probably within the next day or so unless you take immediate action to get your tank under control. Even though the water may look clear and clean, it is likely loaded with ammonia which will kill your fish. If one has died already, that is a bad sign. Please please read through the link in my signature about cycling a tank and stocking a tank properly.
