I did some major plant removal on the 125 . I also removed all the rock . Seeing how fast the chain sword has been growing I've decided to grow the whole bottom with it. I transplanted a bunch to where the rocks were. I also think I might grow in the ludwigia where the amazon sword is and then remove the rest of the swords. It will take a little time but you will see, just give me some time Also the Koi Angels are from Tropics007
