Hi

If you are using Tropica
Aquarium Soil Powder, I think you'll find that it releases ammonia into the water for a few weeks, which wouldn't be good for any livestock. Please note the advice given on Tropica's website:
"Aquarium Soil Powder ensures good and active growth from the beginning, and boosts the red plant shades. It is a complete bottom layer, which can be used without any other types of bottom layer. Aquarium Soil Powder is further an active bottom layer that lowers the pH value and slightly affects the water chemistry. We recommend that you change 25-50% of the water min. twice a week during the first 4 weeks after establishing the aquarium".
You should have been advised of this when you made your purchases.
