Go to your local pool shop, they'll have goo that is used for 'pool tiles'.
I don't think normal tile goo will be good for the fishies.

New to rec.ponds. Hello all.
We are installing a cinder block pond as I type this. It will be sealed
with Hecht Rubber EPDM sealer. My wife found some granite tile on sale
and wants to line the inside with the tile. Hecht says normal tile
adhesive will work against their sealer.
Does anybody know if:
Tile adhesive works underwater?
Will it kill the fish?

Thanks
