Danios Are Nipping Each Other's Fins

[Ilya]

They're nipping each other's fins. And one fish is missing an eye . I'll exchange him at the store today.

Can we take a look at your water atats in ammomia,nitrite,nitrate,and ph.

You need more zebra danio's, when kept in too smaller numbers they will often display unnatural behavior like agression between each other, they are shoaling fish and ideally in your tank should be in a group of at least 6-8 danio's to help prevent behavioral problems like this .
Personally i would keep the danio with the missing eye, it will survive and should heal up fine with a little melafix, good diet and clean water, a missing eye is not a problem for fish like danios.

Like I said yesterday in your last post, you need to increase the amount of danios.

Okay. Well, the eye was missing before I bought it. Just didn't notice it.

I tested my water yesterday. Tiny bit of ammonia (Dur), and a small amount of Nitrate. But the water was a bit soft. (Must be Bogwood)

How long has the tank been set up for?
