Red tiger lotus: not enough light?

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.

 

That's normal! You probably have enough light in the tank for it, though I would fertilize it for healthiest growth (unless you have a fertilized substrate?)

 

Thanks, that's good to know. I just thought it was really odd since all the other leaves have stayed down low, as you can see.

I don't have a fertilized substrate in there, just plain old black blasting sand full of trumpet snails. I've been kind of experimenting with this tank to see how the plants do without them. If They start looking a little iffy, I'll definitely start fertilizing.

 

It looks like your Tiger Lotus has holes in it - or is that just the coloration and it's hard to see on the pic?

 

Yes, two of the 3 oldest leaves do have some holes. They aren't discolored or anything, and none of the other leaves have holes, so I'm not sure if it's a deficiency of something (possibly from the tank at the store?), just old age of the leaves, or maybe my nerite snail just decided to chomp on it a little.

You can see the holes in the top right leaf and around the edges of the bottom left leaf.

 

Holes are often indicative of deficiencies. I would fertilize. My nerites don't munch on my plants.
