It depends a bit on their age. With very young ones I leave the heatlamp on all the time (not $50 one from petshop but 2 for $2 from $2 shop) No filter but lots of water changes on babies but very big filter on adults. No stones for babies but big gravel for adults. Reptile light on for daylight hours on babies (no windows) Basking area by window in sun for adults. Feed good quality and varied food, I always have cuttlefish shell in tank. Feed as much plant as they want when they get interested. They don't eat plant when young. Make sure that you wash your hands after handling as (like many pets) they can carry salmonella.
