I have finally added real plants to my 100 Gallon tank. I got 4 tall sword pants and 2 onion plants. What i need to know is how do i take care of these and the swords have some stem/leaves that are reaching the surface of the tank. I placed these near but not too near the filter ( magnum 350 canister ). I was told the outflow near the plants is a good thing.When and how do you manacure these ? the 2 onion plants, i have on the other side of the tank up front in the corner and in the path of my sponge filter powerheads outflow and they flow gently with that current. I just need to know how to manicure these plants and when, and what additives should i add to the tank. The tank houses loaches, tetras, corys, a couple of tiger barbs ( old and slow) and a couple of guppies. OH, and a blood parrot fish who just lost it's mate after 2 years. The fish are not bothering the plants that i have observed, just enjoying swimming among them. One thing i noticed is the fish seem to have changed for the better with the addition to these plants, less shy or more active i should say.I had plastic amazon swords before which are now gone.
