Unless your fish have been fighting, prominent blood vessels in the tail are caused by water quality issues. A few weeks of clean water and they should heal.

Agree with the above post - what size tank do you keep your goldfish in - how many other fish are in it (if any and what types) and do you check your water parameters? What are your latest readings for ammonia, nitrites & nitrates?

How often do you change your tank water and how much at a time?

Firstly, in addition to the above, is your tank cycled?

I use to change 100% water every week .........I put borewell water ( under ground water ) , I have goldfish ( 4) , pearl scale gold fish 4 , 1 common loach ( its not purchased bt saved as it was fallen from a fish trader's tank ) , 2 common plecos .Tank is artficially planted bt going to put natural plants shortly. Because the water used is from under ground water so i don't check the water quality ( assumed that ground water is free of chlorine and other chemicals). I have 15 gallon tank ut going to change it in a 30 gallon shortly. My fishes are with me from 2 yrs back and they dont had any problem yet.
