Given that almost nothing I do is "appropriate" heh... plant care I'll leave towards OFL for the most parts.
Depending on how much nutrition and light the wendtii/crypts will grow up to two feet tall... basically regulate growth with light. I use a glass lid on my 10R so I can move the light between back and front about once a day. It keeps the plants moving around. Crypts mostly will turn leaves at a light source so you can use side lighting aimed in as well.
Bronze will spread out quite a bit. I have one that is alone in the bottom of a Hex 5 and it touches all the sides happily but doesn't like intense light.
Most of them are 1.0 to 1.8watt per gallon plants.
