snail & betta

how about i grabbed a couple snails today while at the store, put one in my
bigger betta's tank, he wanted to attack it, i gave him a second to realise
it was not food, but he was dead set on killing it, the little sh*t, so the
snail was in there a matter of five minutes, he would not even let it come
out from its shell to move, i moved it to the females tank, they dont seem
to notice it but i guess now i will watch them in case. Is that normal for a
betta to act that way towards a snail, i guess they all have different ideas
of what is ok in their tanks..

update gourami, he is now laying on the bottom of the tank not swimming
around, i feel so bad wish there was something i could do for him but i
think the lack of oxygen when he was out, and the brush burn on his top fin
may due him in, i put a little extra salt in the tank, i usualy put a little
less in the tank normaly then it says to incase i need to use it for
something then i can use more.
