I'm embarking on my first planted tank and I'm having issues!! Firstly, I can't keep my fishies from destroying any of my plants! The only one they leave alone is the sword, and there's my next issue! The sword is taking over my tank! I had to cut some of the stems as they were coming out of the top - will the leaves regrow or will I be left with stalks? (Silly question??). Is there a plant/s that will survive without being ripped apart by my fish? And how do I make cuttings to put into my other tanks? :-/
