Generally, predatory fishes don't interfere too much with live plants. It's mostly when you keep herbivores that you have to resort to fake plants if you want the looks. I personally think that fake plants look even more fake when placed next to a live plant. Thus, I would not recommend to use both in the same tank.true, but for keeping predatory fishes , i still feel fake plants are suitable too, provided its aquarium safe. some plantedtank do mix and match live and fake plants too
