This tree like thing started growing on the rock that my pods grow on. There is now 3 of them and the tallest is 5 " now.
Can anyone tell me what it is?

Is that a bad thing to have in your tank.

No, it's good. It probably won't be around for very long though, because MANY things like to eat it. So, enjoy it while you have it and then when it gets eaten be glad for the natural food source.
