Nymphea lotus - earlier called Nymphea zenkerii. Popular name "Tiger Lotus" (but it is not a Lotus). Note the small, triangular leaf.
- just plant it in the gravel/substrate, covered so just the sprout is above. It will produce more or less spotted leaves of green or red-brown. To ensure good growth, you should feed it bottom fertilizer (= root tabs), since it is one of the greediest tank-plants, needing a lot of nutrients.
- It can produce a white, scented flower if allowed to grow big enough. It's a night flower, though, only open one night (not worth it, actually !!)
