As
@Circus mentioned, the size of your rank is important...(lol, just joshin’)
But the point is well brought up, there are a whole bunch of factors to adding fish to an aquarium.
Some plants will uptake a bit of ammonia, but you want to make sure your tank is fully cycled and has the bacteria to convert ammonia to nitrite and nitrite to nitrate, which plants will more readily use.
that being said, plants are all different and consume nutrients at different rates.
instead of asking how many of what kind of fish you should add to the tank, I think you should do some more research on the general principles of how aquariums function.
this will in turn broaden your knowledge base and allow you to ask more targeted and specific questions with necessary details that our members can more accurately answer for you.
you’ll also become a better hobbyist for it, and your fish will thank you for it.
some good starting points would be the nitrogen cycle and quarantining fish.
good luck! And if you need more direction, this forum is full of great articles and thread to get you started.
