Answer
Hi Nicole,

While I'm not so much an expert on planted tanks... A little bit more info would be helpful!

Like what species of plants you are currently keeping?
What kind of additives do you add to the water (like fertilizers for the plants)?

And if you need advice on keeping your fish alive... Some info like -

What species were you trying to keep?
How often did you do water changes?
Was the tank cycled?

These little bits of information will really help me offer more advice! :-)

Good luck!
Susan~
