Maximum number of new fish to introduce to a tank?

[phish food]

Hi all,
I just cycled my 90 gallon planted tank and added 5 rosy barbs two days ago.
They are very active and swim to all parts of the tank. Yesterday, I was tempted to get more fish, and added 3 more rosy barbs and 4 panda corydoras. They are also doing very well.

Someone on the forum is selling tetras, which I want to get, but the whole lot would be 33 more fish. Is it safe to add them all at one go?
Is it too many fish for my tank?

Additional details: My 3' x 2' x 2' tank was planted on 4th December, I added bacteria (nutrafin brand) to cycle it.

I did not test the water, though, but the fish seem to be faring well. Is it really necessary to test the water? The test kits seem rather expensive.

Thanks! But I also wish to know if the fish can be introduced all at once, or has to be a few at a time?

Best is that you add in your fishes gradually because the current BB colony might not support the bio waste. its better to invest on some test kit for your fish tank so that you can keep track how is the water parameter going.
