Bathroom/shower Sealent Safe?

[CoolWater]

Hey

I just noticed some water proof sealant in the back of the cupboard.
It says it is for bathrooms and showers.

Is it safe to be used in the presence of fish?
No real reason, i just wondered that’s all, and not knowing is getting to me.

Thanks, and sorry for random question

Not safe as the anti fungal parts of it will prevent your bacteria forming well in the filter as well as (I believe) being harmful to the fish,

Totally agree, don't attempt to use it in an aquatic environment.
