:iagree:Untreated water, unacclimated fish= untimely death.
lesson learned,
Be more patient, wait for the tank to be cycled and
get a test kit before putting any livestock in..
It is my first time have a new tank set up with new filter..
I have the other 2 tanks for a couple of months but It was started with a stabilized substrate and filter media..
So this is why cycling is important, now I get it..
I was just so excited to see fishes in my tank, and now I see dead fishes :wall:
Emmmm...correct me if I'm wrong but you have other tanks in which the cycle is established/complete.
Move some filter media and substrate into this new tank. Do a large water change. Continue testing for ammonia/nitrite etc. until you are sure it is cycled up.
my poor fishes..
I dont have established filter here, perhaps I can start with plant first?
I read somewhere plant helps to do the cycle..
