Would depend in large part on how long the tank has been running with fish.
If the tank with fish is less than a month old, I would suggest changing 50 percent once each day or every other day until the tank has cycled.
I Would recommend reading up on "cycling a new aquarium".
I would invest in a test kit such as the API freshwater Master kit so that I could test my water for toxins such as ammonia and nitrites which should read as close to zero as possible until the tank has cycled at which time they should test zero.
Would use conditioner such as PRIME or AMQUEL+ for new water added to the aquarium. Both will detoxify ammonia and nitrites created by the fish/fish food.
If your tank has cycled,,then you should be performing 30 to 50 percent water changes once each week to dilute/remove excess organics from fish waste(poop) and fish food.

The most important medication in your fish medicine cabinet is.. Clean water.

Assuming the tank is cycled I'd be doing 30% once a week with a good water conditioner like Prime added afterward. I'd also be looking for a new home for the Pleco. 3" is a baby for that fish. It will outgrow a 38 fairly quickly.

Agree with rehoming the pleco. I had one in my 45 gallon hex. before I knew better. He outgrew it pretty quickly.

Animal testing is a terrible idea; they get all nervous and give the wrong answers.
