I have a red tiger lotus in a 10 gallon tank being lit by 2 6500k 60w equivalent CFL bulbs. It's been growing quickly ever since I bought it as a bulb with 3 tiny leaves on it. I don't use any fertilizers. What I'm wondering about is, as you can see in the picture, it's sent a single leaf up to the surface, which just happened over the course of the last 3 days. This is the first time it's done this, and I'm wondering if its because the plant isn't getting enough light and is trying to get more. I assumed my lighting was fine, since the hairgrass and micro sword I have in the same tank is thriving, and I was always under the impression they had much higher light requirements. The other leaves all seem perfectly healthy from what I can tell, except for two of the older ones that have a few holes in them.
