Hi and welcome, low maintenace all depends on the fish and plants, i would go for a community planted tank with sword plants, tiger lotus and maybe some val and crypts, as for fish there is 4 basic types need for low maintenace , algae eaters (bristlenose,whiptail,siamese algae eaters) then clean up crew (cories ,loaches) then the main fish (angels, gouramis, anything that is a centre place fish ) then last of all the sub -main fish ( usual choosen from the main fish, for example i had discus so i have rams and rummery nose as mine ) ok is that enough 8)
