I have 8 Zebra Danios and one of them recently has become almost like a loner. And his pelvic fin looks... yellowish. I don't have a QT so what should I do. I have Stress Coat+ but that's it. So should I be worried?

I'm sorry your danio is worrying you. I know you don't have a q tank, but it would be a really good idea to get one.
If he's getting ill, there's a good chance the others will pick on his.
A Q tank doesn't have to be expensive or elaborate.
Here's an example of a Quick and dirty quarantine setup

With all that said, is your aquarium info correct? If so, he could be feeling the effects of an uncycled tank. Daily water changes with Prime until your tank is fully cycled would be recommended.

If he is getting sick, Q him. Since there aren't more definite symptoms, keep your eye on him for now.

Good luck, I hope he feels better soon.

Well I just might have to invest in one.. cause upon further inspection one of my other danios is just kinda swimming slowly. My info is correct but a couple days old. I'm gonna recheck them in the morning before the water change. ammonia is going down but very slowly.... mini cycles... gah.

Yuck, hate them. Good luck

The Danio didn't make it. It could have been a nitrite spike. I'm not sure.

I removed Java Moss and added some rocks... made it look... cleaner...
