Did you buy this from your LFS?
I wonder if half of the stores even know what it is their selling.
It is Syngonium ,Not a true aquarium plant. It will rot, die and pollute your tank if left in.
Will go ok for a few weeks in cooler water but does not like warmer water temps. It will start to go brown and die.
Looks great in frog setups etc , and will last alot longer if grown semi submersed but will eventually die.
In short , it is a popular pot plant, and in a pot in your living room is where it will be best.
Ps, i hope that you didnt pay to much, as you can buy these as babby plants at the red shed for $2.00
