snail and danios dieing

[Greater-Ajax]

So my sail, that I have had for about a week died same with 3 out of 6 danios. My mom brought the danios back so we have 6 now, but I dont know. One danio died this morning along with the snail, and 2 died 3 days back, had no idea what happened, but when the danio and snail died, I got vary worried.

They are all in a 10 gallon tank with a moss ball and bubble system.

Ammonia:0
ph: 7.5
Nitrate: 5
Nitrite: less then 0.1


Please, they are not showing any signs of sickness, please help.

Usually when adding schooling fish such as danios you add 3 at a time. For some reason they go canablistic, and peck at some of there school. your snail death is common too, some snails are unhealthy when purchased but there is no way to tell. Oh and do you have a filter on the tank or is it just a bubbler?

We got the snail from a friend, did not know they die so easily, never had one before. And in regards to the they a zebra's, and non of the dead ones had any bites, or nipped fins. And yes I do have a carbon filter.

Ok, even if they dont have nip marks, they are jus harassed a lot. They could have been bad stock too. I would do a water change and watch the parameters

 

[Greater-Ajax]

okay, I will keep an eye on them, and the parameters.

thank you so vary much!
