I have several of those Peacock Ferns from the tubes from PetSmart. Every week they mark some as 50% off. Some of them look pretty bad, but I got one that looked great and is doing good in my 75 gal which is in DSM. I have since picked up 4 more (all at 50% off) and they are all doing well also
It will look great now that you are growing it emersed in the dsm setup, but after the flood, it will rot and die. Google peacock fern, you'll find all the info on it. I know my local p.s. now has stickers on the peacock fern that say "semi-aquatic".
Tony, you need dhg? I can hook ya up
