Neither are rocks, a perfect replica!

I like your idea it sounds pretty cool! I am not educated in the fish department for aquarium stuff probably lots of KZfaq videos on the topic! And I can help you out

@@ThriftHacker it’s ok if you don’t know about aquarium stuff my main concern is how can i give the look of cave to this expandable foam material if you have any complete video plz do share link

@DhavitChandra in that regard it's pretty easy you can buy can of this stuff and just make some samples it dries pretty quick you can carve it using exacto knife to give textured look.. maybe glue some popsicle sticks to give basic shape you want then spray foam over it to make cave. Or use wire,etc

@@ThriftHacker nice thanks 🙏

Cement

In this particular application underside of the fake rock had to be carved out

@@ThriftHacker oh I see

But he is a new chanel don’t hate
