So I am new to the forum and new to aquariums with the help of a friend getting me set up.
My situation is as follows and I think I know the problem, but I wanted to check with others that know what they're doing!
I had 8 neons in a 4 gallon Biorb mini
Got a new 10 gallon tank and moved the neons over
Gave it time to set up and well, neons are small wanted to expand out once it was established
Added 3 red wag platys and 3 sunburst platys
(The problem I think was that when I added them I also added the water from Petsmart)
For about 24 hours they were alright, then the next day they started to die one by one. (Yesterday)
The platys are ok.
I moved them to another fish tank, a 2 gallon, the 4 surviving neons and this morning, 2 had died.
I did a total water change on my 10 gallon with distilled water and the platys are just fine and loving it. I have 1 neon about ready to die and 1 left.
My question is, was it the petsmart water that killed them, obviously the platys had been living in it and are fine still, the neons would be a new experience and well, I only have 1 left and maybe a second one.....
I would like to add neons to the tank again, but I'm going to guess I shouldn't mix the store water this time.....
