Natural Aquarium 2 Week Update

It’s been 2 weeks since putting together this 20 gallon natural aquarium. The plants are growing like crazy and the microfauna are working on establishing themselves in the environment. The water hardness has gone up a little due to the limestone rocks, this is expected. We will see just how high it goes over time.
I plan on adding fish in a week or two. What should I add??? I breed platys, guppies and swordtails. It will probably be one of those. Also the goal would be to feed very little, so I won’t be adding too many.
If you want to learn more about the microscopic organisms in your aquarium or would like to purchase a microfauna culture check out our website.
