Zebra Danios

[GRJ]

Hi, i had my tank running 7 days and added 2 zebra danios and 3 platys to start the cycling process 2 days ago. I have done a 10% water change today and added the dechlorinater and some ammo lock. The all seem fine but the one zebra is just staying at the top corner of the tank while the other one is swimming around. I have fed them and he has taken some food and been out a couple of times to have a look around but keeps retreating back to the corner. Is this normal behaviour or not? Thanks. GRJ.

No the cycle taking it toll on him, there never any guarantee's that a fish will make it through a cycle.
They have to go through the ammonia, and nitrite process, it can shut there immuney system down.
Increase aeration and add salt, one teaspoon to 5 gallons.
