What should I do with a neglected tropical fish I saw?

  I went to see a short sale house yesterday. No one is living in the house. There were clothes everywhere and broken furniture. Half of the lighting in the house did not turn on. I went down to see the basement and to my surprise there was a huge tropical fish. The size of two hand lengths.



The lights in the basement did not turn on. I used my phone to take a closer look. This fish was in a huge dirty fish tank and this fish clearly had one eye missing. It really made me sad. This once beautifulal fish is clearly being neglected.



I am not not going to buy the home but, I am just so upset about the neglect of this beautiful fish. Any suggestions what I should do? Does the Humain Society deal with tropical fish? I fear that if i don't do something . No one will and this fish will die.
I would call them. At least tell them.



"Two hand lengths" That doesn't say much about size. How big is the fish, what does it look like? You might need to know the species.
Yes they deal with fish, too. Call them right away !
