Please help me help my dwarf gourami

[jeneequah]

Hi everyone,
First time posting...

Here's a picture of my dwarf gourami, he has a weird dark edge to his fin. Just developed 2 days ago. He's acting normal and eating well... I thought fin rot, which i've never encountered but google tells me the edges of his fin would be white... He get along well with all his tank mates. Anyone know what's wrong with him?

I would say it's fin rot, all fin rot I have dealt with is black around the edges. One way to cure it is to keep the water super clean, and another way is to use Melafix I believe.
Good luck!

can't really tell from the pic...describe the fin a bit more...does it look like something is eating away at it? or is still in good shape but has the dark coloration?

Welcome to AA. It is very hard to tell from the picture exactly what is going on. First I need to know what size tank and did you test for ammonia, nitrite and nitrate? How often are you doing water changes and what are the tankmates?
