i got a couple more plants and now i have 4 snales.. that i know of.. Should i kill them off or keep them ore what...??

You should'nt kill them. Were they on the plant when you got the snails? If u don't want to kill them, then u should give them away.

I agree no need for killing them,if your so concern with
them i would bring them back to the pet store or fish store you got the plants at,the next time you go...Or you could always give them to someone who would love to have them.

Yes don't kill them! I know it sounds weird but put yourself in their place.

The pet store may take them, and if you don't want them in your tank (if they don't take them back) you can always get some sort of stand-in snail tank (like a clear plastic tub or something that you store things in) and then you can still have them, not have to see them in your main tank, and see how cute snails are.

i wasn't planning on killing them.. i'm too much of a softie to do that. but my dad said i should and i was wondering if you all thought that i should too. my main concern is that there so tiny that my goldie might eat them. i have a triangular plastic aquarium made for bettas, i guess i could always put them in there...
