Adding fish to my cycled aquarium

[alcidmr]

Hey everyone question I have four Cory’s in my 20 G High aquarium and want to add more fish and I want endless, how many can I put in my tank at once, and by the way they sale them by 10 fish, Is that ok

If the tank has been running for a few weeks it will be fine. Keep an eye on the ammonia just in case.

Yeah it has been cycled Just been scared to add fish for two reasons don’t have a quarantine tank and scare to mess up by adding more fish, like I mention I have four albino corydoras but ok thanks I’ll keep testing after I get more fish

You can always treat the whole tank with the med-trio when adding the new fish. Or, just watch closely for any trouble and have meds on hand to treat if anything comes up.

OP, maybe this well help you. I've found it useful: https://aqadvisor.com/

What I am doing for my 10G is to add a few fish at a time and monitor the water levels. I started 2 weeks ago by adding two neon tetras (I know, I should have added more so they can school...) and then just sitting back. Then a week later, with tank water stats stable, I then added 3 female guppies. If the tank holds steady (aside from some pH fluctuations) I'll end up adding a single male guppy. :)

 

Good luck with your tank!

if you can only get them in 10, i would a few days or so before you get them, increase your feeding amount slightly. this will help bump up your bacteria colony as they now have more food, and will multiply to compensate..
