I can't buy fish at our PetSmart because they use RO water. I am on well water and do acclimate but I have never had any luck with their fish. I have found a local lfs that has been great. Not sure where you are located but it might be worth the wait and drive to find a good lfs. One that truly cares about the fish. I am so tempted to buy a fish at PetSmart but they always die in my water.
I currently have a 55 cichlid tank which is overstocked due to babies.
a 29 with 3 Angel, and a long skirt tetra
a 20 tall with 1 Angel, 2 flame gourami, 2 peppered cories
a 10 quarantine with a cichlid to keep it cycled
and a new 30 long that I am trying to decided what to put in it.
