Can we use fiber toughened glass for aquarium for tropical fishes?

Do you mean fiberglass? Sure, you can use fiberglass to make an aquarium. For big tanks it is much lighter than all-glass. They even have transparent fiberglass. Or you make it all fiberglass but have one face clear acrylic or glass to save overall weight on the tank.
It lasts a long time and does not corrode.
Just make sure it is fully cured before filling.
I once has a fiberglass aquarium for blind cave fish. I also have a water tank made from fiberglass used for the home drinking water well system.
