Cloud terrarium

This used to be an aquarium for our killifish, but my girlfriend and I turned it into our first terrarium 🌱

Conditions:
• 30 °C (heatwave helps )
• ~80% humidity

Substrate:
• 5 cm pumice (pouzzolane)
• 10 cm plant mix (⅓ perlite, ⅓ coconut fiber, ⅓ potting soil)

Plants:
• Begonia rex
• Monstera adansonii
• Adiantum capillus-veneris (Capillaire de Montpellier)
• Syngonium sp.
• Fittonia
• Caladium
• Alocasia cuprea
• Forest moss

Any advice is welcome!
