Holey Tiger Lotus, Batman!
I've got a red tiger lotus that was doing great, with growth right from the beginning that can only be described as explosive. Now, virtually all of the leaves have holes. The holes start out looking like a cigarette burn (small hole with crispy looking edges), then expand until the leave is reduced to a small triangle. There is some new growth, but it looks kind of anemic - small leaves that don't have good color. I've noticed the same problem to a lesser degree with my the only other red plant in the tank - A. reineckii - some little holes, but not as much destruction.
I added a couple of Flourish root tabs a couple of weeks ago, but nothing has really changed as far as I can tell. I haven't really been fertilizing at all; I've been a little skittish about it since I had an algae problem.
The tank is a 40 regular, heavily planted. Jebo 2X96 watt lighting. Small gravel substrate mixed with Eco Complete (less than 50%). It's been up and running for about six months.
