Not sure what these things r

[Calebb8133]

There r two new things in my tank pictures below! Not sure how the got there or what they are. The shell looking thing is not owned by a hermit or anything never seen it before
The spider web like things have popped up every now and then but I just break them and they go away but there is alot in my tank right now so thought I would include it anyway

Also helps to circle whatever you are talking about.
