Hi, I'm 2 years into the hobby and I just decided to try zebra danios for 20g heavily planted tank. I did a water change Friday and tested my ammonia level this morning and it was .25ppm. I have 6 in a 20g along with 4 cories and a single mystery snail. I've had my danios for little over a week now and one seems a little out of sorts? It won't eat and it seems to be avoiding the others. He keeps to the surface a little more than the others but isn't swimming as actively as they are. They just gobbled down some frozen bloodworms this morning, but that one danio didn't even touch them.
Got any ideas? The danio doesn't have any indications of illness outside the body.
I was just wondering if 6 was too little of a shoal? I heard they do better in at least 12 or more.
Maybe that's its problem?
Thanks in advance!
