Nope..just regular ole table salt..not kosher.
The coral came from much larger peices of coral that have been in a freshwater tank for probably 8-9 years..I'd think anything that could of leeched from them would long be gone now?
Yeah..I painted the back of the tank.
I never thought about the betta getting stuck in the coral. I might just end up putting an anubias in each side. or maybe a black and white dragon..that would be sweet! I still need to add some entertainment for the fish..probably some plants.
