White patch on Dwarf Gourami

[MartynC95]

Hi,

I purchased 2 Dwarf Gourami and 2 Red Dwarf Gourami 4 days ago and all has been going great, eating really well and very active.

This afternoon I noticed a white patch (pictures below) on one of my Dwarf Gourami that wasn't there last night, or even this morning (I don't think). I am concerned it could be Columnaris, but I am very inexperienced with these being my first 4 fish...

My other thought is that he has scratched himself on one of the rocks in the tank?

Anyone able to shed any light on this and if so what it could be?

My tank conditions are:
PH 7.5
Nitrite 0
Nitrate 5
Ammonia 0
KH 3
GH 8

Thanks

looks like a fungal infeftion to me

try some api fungus cure. it saved one of my bettas before. hopefully it'll have the same effect on your dwarf gourami.
