so my ramsgorn snail died and disintigrated. I'm going to do a water change tomarro. I think the apple snail is dead too. He hasnt moved all day. his trap door (

) is open. But his body hasnt separated from the she'll or anything. This white fuzzy stuff came from him, and his she'll was "dusty". Also, is this stuff ( disintigrating snails and the like) lethal to my other fish

Thanks!!!
P.s. If I decide to get another snail what do I have to do differently so that they live

Also, my betts has started acting a tad lethargic could this be related
