I personaly dont buy the theory of incompatibility of keeeping specific plants .
Having spend all my 20 year aquarium carrier mostly read about them and keeping them (that is until i discover discus ) i have come to conclusion that they are just one big enigma to me and that they grow how they want and when they want .
In an completly unchanged enviroment one plant starts thriving and take off the entire tank and the next period it barely survive or just dies off . Then another plant starts to be no.1 grower just to start rotting the next moment .
i totaly gave up on choosing plant list my self and started planting many diferent species and let the nature tell which one lives , thrives, survives or dies
Not very helping to this thread i know , but just wanted to share my 20 year experience with plants and that is as Socrates would say "now i know that i don't know anything"
