I have a 5 gallon tank and I bought a 15W bulb to go in the light fixture. I don't remember the brand, but I bought it at Petsmart. I do remember that it said something about improves color of fish. And at first it made the aquarium look great. But within a month or so I noticed it didn't like up like it use to.
Is there a better brand I can buy or is this the normal lifespan of the bulb.
