How long, do you have to wait to put fish in? Its a 20 gallon long tank
Okay, thanks for the help. Im new to this so im just curious.Kinda an open question. Tank must be fed then cycled to get bacteria. Your method of doing that will determine time.![]()

Yes, fish live longer and happier lives if they are installed in a properly cycled tank, ime. Slow and cycled wins the survivor award and avoids burying fishes.Its not really about time, but about how long it takes ammonia to rise and fall, and that depends on how you cycle the tank, and there are many ways to cycle a tank. Personally speaking, just for me, I generally wait about 3-4 weeks before adding the first fish. It is important to cycle the tank first before adding fish.
Note that the cycling segment uses Fish In cycling that may generate some very disapproving reactions from some users…Check out on YouTube BRS 52 weeks of reefing it will walk you through all the steps. Very informative and easy to follow.
Thank you it’s been almost two years since I watched it and remember it was very informative. I don’t remember that probably because I started all with live rock.Note that the cycling segment uses Fish In cycling that may generate some very disapproving reactions from some users…
