My freshwater tank has 20ppm nitrate and 0 ammonia and nitrite. can I add all my fish at once?

1. A tank needs to be cycled for 4-6 weeks before a new fish is introduced, this will help with the nitrogen cycle. 2.

A nitrogen cycle is this your fish releases ammonia (which is there form of pee) the amonia then turns into nitrites a deadly toxin which then turns into nitrate an even deadler toxin the way to remove these toxins are filters and water changes 3. Bettas don't like strong currents because their fins are so flimsy for swimming, their tail can also get cought in the pump and shred him. 4.

Try a low power filter and go buy some quick start from petco/petsmart this will help kick start the benifitial becteria and maybe save your bettas life.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
