@ diruak - IAL is a leaf, that creates a natural habitat type water for bettas, and it is supposed to be a general tonic for fish in general. It is supposed to help induce spawning, help heal wounds in fish, such as fin rot and whatnot, and it does work great. All of my males made HUGE bubble nests, and my females barred up when I added them to their tanks, but I hate the look of the leaves in the tank, and it makes the water a little nasty after a few days. To me, This method is much easier, and a lot cheaper than buying it from the store for $x.xx.
@ Katana - It isn't a drink, see above, and it isn't a water cleaner, see above also :)
