My Clown has a growth
Iím new to the marine hobby. Iíve only had my tank for a few months. Itís a 200l tank with 20kg of live rock and 10kg of ocean rock. All water parameters are as they should be - Salinity 1.023, PH 8.1, Nitrite, Nitrate and Ammonia 0.
In the tank I have 2 tank bread percula clown fish (had for 2 weeks) 3 red leg dwarf hermits and 5 turbo snails.
A couple of days ago I noticed a brownish spot on one of my clown fish's face near his gill. By the next day it had more than doubled in size and was lighter in color, looked like some sort of growth? The other clown does not have anything. The one which does doesn't seem to be affected by it. He is still active and feeding ok and his breathing doesn't look any faster. His eyes are clear and he is not trying to scratch against anything. Has anyone got any ideas?? Do you think it could be Lymphocystis (cauliflower disease)? The growth is quite warty looking but it is brown in color. Do you think a fresh water dip may help?
