Hi! I am new to this forum, and an aquatic plant newbie. I bought some kind of Amazon sword plant from Petco, and have noticed that since I planted it in my small betta fish aquarium (3 gallon), all new leaves are much thinner, almost transparent, compared to the original leaves. What gives? I use API Leaf Zone. I am not sure what else I need to do (or not do) to keep the leaves healthy. Or maybe this isn't a sign of poor health...? I don't know. The plant keeps producing new leaves, they are just so much thinner than the others.

Any suggestions? And remember -- I am a newbie, so even if you think its the most obvious, basic information, chances are I don't already know it! I'll take it!

Thanks!
