fish losing slime coat?
Posted: Wed May 18, 2011 1:26 pm
I bought new fish a few months ago and they all died after a few days. their skin became discoloured at a small point on each and then spread across the fish rapidly. before I bought these fish no fish had died in my tank for years. I tested the water after this incident and found the ammonia to be a little high. after water changes and different treatments the ammonia finally got back to 0. I then bought some new fish on Saturday (before which I checked the water parameters which all came out normal) however now the same thing is happening to the new fish. what could be the cause I think the discoloured patch of skin is the slime coat being lost but what could be the cause of this in the first place.
any help would be greatly appreciated.
