please help me

I have 1 female and1 male bristlenose Pleco
How do I get them to breed

Water Parameters are fine
They are old enough
They do have a cave

With plecos, its kind if hard to really "make" them breed, however, if theyre mature enough and have the right water temp/cave then should get to it themselves.

How long should/could it take

Depends on the fish, if the plecos are ready and want to have some fry, then they might be doing it as we speak but it could also take weeks, days. Only time will tell. Just make sure they're getting food and other fish aren't stressing them out.

I've always found that a 20-30% water change with cooler water trickled into the tank (as opposed to just poured in) helps to stimulate many different species to spawn. Makes most of the livebearers pop too. As already said though, diet is the key to spawning success. Happy well conditioned fish will spawn with no adverse health issues.
Good luck dude
