8 month old low tech aquarium

UNS 60L, with monte carlo carpet, red crypts, hydrocotyle, weeping moss, and salvinia minima. Terrestrial plants are some kind of scindapsus, syngonium, pothos, dragon's tongue, and a heartleaf philodendron, some of which is growing in a HOB with filter media removed. No CO2. I haven't done a water change in maybe 4 months now.

Stocked with crystal red shrimp, some orange neocaridina, pygmy cories, and ramshorn snails.
