Thanks for the help, I won't add any other frogs unless we find another young PCF. I didn't want to add a pacman frog, I was just using it as an example (from what I have read) of a bad combo. But I DID want to add the White's, but from what you guys say, I can see it being a bad idea, so I won't do that.

I also wont add fertilizer since it seems the cocofiber should suffice. Thanks for that! I'll look into bulbs
