Hey all, I have about 5 nano community tanks, and haven’t lost a fish in over a year. I tried setting up a new tank for my roommate but we are down to 2 guppies left out of the 5 we bought last Friday.
I use old filter media to cycle along with API Quick Start. Did daily water changes for the first three days and did the level 2 salt treatment listed on this website. This isn’t the first time I’ve lost guppies, as I lost some in an established tank due to me over medicating it.
This time around, though, I can’t figure out what I did wrong. My best guess is I just got a bad batch of them, but I figured I’d post on here and see if I did anything wrong.
Tank Size: 10 Gallon
pH: 7-7.2
gH/kH: 150/40
Temperature: fluctuates between 77-80 due to water changes and using a brand of heater I'm not used to.
Ammonia/Nitrite/Nitrate: 0/0/10ppm
Any general tips or ideas as to why I can’t keep guppies alive?
