I decided to get a tiger lotus 3 weeks ago. Since I've had fish aquariums all my life. 12 year old gold fish and a 3 year old kili louch, I seem to do ok in the fish department. But this lotus is growing new leaves that spread out on the bottom instead of rising. I'm currently growing in gravel. I need some advise on substrate and why this plant is doing this. I have 5 fish in the tank 2 painted glass 2 cat fish and 1 rio tetra
