Any Anubias, any Microsorum, Bolbitis heudeloti, Ceratophyllum demersum/submersum, any Cryptocoryne, Najas guadalupensis... for these plants 20 lm/l is fine.
If you want Corydoras keep in mind they want soft sand a dedicated beach that is half the size of the floor area, preferably lengthwise. You will have to favour the smallest Corydoras such as habrosus if your tank is less than 100 cm long. Also they are schooling fishes that want to be at least 10 individuals.
