I have recntly moved into a new house and the old owners claim that there are 3 fishys in the water. two big ones and a lidal one . they hardly ever come out tho .
I have put up a topic on the pond and it porr conditions.
Now I want to talk about one particullar fish . Its a big long gold fish .. but its just not moving any where.
it floats as if it is almost dead. .. i got it to move just enough for me to notice and big white/light orange lumpy LUMP on its back . I have know Idea waht this it or how it got there . i have been in this house for about a week and a half now and i swear that wasnt thurr wen i see it the first time.
How do i get rid of it ?

And how did it get like that / or is it completely normal and im over exaggerating cos the pond is dirty.
