I would say toxic to fish & maybe plants as well.
Don't know about Silicone II - but back in the 60's when I was building
all of my own aquariums (1 to 250 gallon) all of the silicones except Dow
Corning had ARSENIC in them to prevent mold formation.
The marine silicones may have tributal tin (TBT) which prevents barnacles
& algae from attaching to boat hulls.
If it's not safe for fish I don't think I would use it for my plants either.
The larger tubes for use in caulking guns are a better deal for your
money. Most can have soemething stuck over or in the tip to prevent drying
out in between uses.
Check the labels & see if they say they inhibit mold & mildew - if so
don't use them.
