Hi everyone,

My name is Janize and I have a few questions.

1. How do I know when a molly and guppy is going to give birth, and when danios are going to lay eggs?
2. Can Zebra danios en neon danios mix?
3. I have a few plants in my aquarium and some of there leaves started to turn black? What's the cause?

Have a wonderful day

(^^,)
