Can you normal average house pets get a long with reptiles?

Can your normal average house pet like cats, dogs, and fish live in harmony and peacefully with reptiles under "your" supervision, i've even heard that fish could be housed together with turtles, aquatic reptiles, and amphibians is that true? i've even seen a lot of videos on youtube with people's cats and dogs getting along well with their lizards and stuff like their bearded dragons and i do know that snakes will not naturally get a long with a dog or a cat since they would be to freaked out by them or if it is a large snake like a boa, retic, burmese, rock python, or anaconda then they'll be happy to eat the dog or the cat but the reason why i'm asking this question is because i'll be getting a red-tail boa soon and a green tree python and emerald tree boa in the future and i'll be getting some dogs and maybe two cats as well so i was just wondering if the snakes be ok with the dogs and the cats, i'm not going to let the dogs or cats near the snakes when they're out of their enclosures or anything i just wanted to know.
