My 72 litre (circa 20 gal) South American fish tank

Equipment consists of a 15 watt LED lamp, a 30 W heater and an Eheim Pickup 160 internal filter.
Inhabitants are six Echinodoruses, a fair amount of Najas (plants), 10 Neon tetras, 5 Pygmy cories(C. pygmaeus), 4 Helmet snails and a ton of smaller snails (animals).

It looks nice How long has it been set up?

@gentle lemur it's just a month old.
