hi i was wondering how easy it is to change from silk plants to realy plants, i love the look of real plants and i only have silk plants at the moment but i was wondering how easy they are to change i don't want to put my hand in the tank and grab them as surely this could contaminate the waters and stress the fish out and im not sure which ones to get and how easy they are to look after. i have 4 bottom feeders in this tank aswell will this disturb the tank to much for them ? any help would be appricated
