White patch on betta
Got a new betta yesterday and this patch seems to have appeared overnight.
It was there yesterday but it was only a slight discoloration.
Is this some sort of fungal infection or just damage from his new environment? Columnaris?
he seems really energetic, he is also eating.
tank is 15 gallon with pond and assassin snails only.
I ordered some api bettafix, just incase it gets worse, I would rather not have to use it.
