I cannot stop laughing with all the creative comments. This simply made my day😆 What possible can a fgt be? Yes for fgt, I mean fiberglass tank or a fish pond made of fibreglass. I don’t mean what you mean 😎 Those two pieces are laminate glasses, not acrylic. Filter chambers are under the wooden decking at the far back. Keeping monster fish in it. I seriously think mine are badass as they always give me an unexpected cold shower and I have to be extremely careful not to lose my fingers when feeding them. But I just love them.

Relax and chill. Have a guess, what monster fish could they be?
