Bn With Funny White Patches

[mattlee]

a while ago i added an L200 to my tank and it went all scabby eventually got sunken eyes and died. not long after this i noticed by BN had a similar issue. it seemed to get better without any treatment but its worse than ever now...


im currently setting up a treatment tank for it but im unsure of what to treat him for it isnt cotton wooly so im guessing not a fungus but possible bacterial or maybe columnaris.

all the other fish seem fine and all very healthy.

here is the L200

and here is the BN

looking at the 2 pics together the issues seem to be different in appearance the bn is much more white and the L200 was milky/clear ish....

im guessing that the L200 had the initial issue and as it wasnt quarentined has passed it onto the bn, maybe in a dominance battle where the bn may have received a small cut

the bn is still acting normal and feeding ok but it has lost its stunning colouration and gone a bit darker than it was
