We have this odd thing occurring in our tank. I beleive the plant is a cabomba or in that family. Its been very happy and content for last 4 months(since entered into tank). Now it seems to be mutating at its most mature points. The fine light green leaves have gone dark green and balooned into an alien type mutation.Will the leaves explode and cause carnage amonst the fish - or is this a normal part of plant maturation. How can i find out what is occurring. Jenna
