I have a Beta fish named Tango. He is my fifth fish and I have never had an algae problem, but now I have algae in his tank. I had no problem last year when he had the same tank. The only thing that has changed with his environment was lighting. He n
Too much light, whether natural or artificial (green/yellow LEDs can worsen the issue) can sometimes cause an increase in algae growth. Moving the light around a bit to see if it helps, changing to a different type of LED, or just cleaning the tank more regularly/adding in algae eaters may help.

I have a 20 gallon tank. I'm thinking of buying +5 fish. Which fish could I buy and what would I need for the fish and tank?
A fish tank will need a filter, a light/hood and a heater. Make sure the filter is rated for at least twice the tank volume. The heater should be adjustable since water temperature will depend on the species of fish. Good "starter" fish include Tetras, Mollies, Danios or Tetras. A new tank should be set up and left running empty for several weeks before adding fish. A pinch of flake food can be sprinkled in daily. This "cycling" will allow a population of beneficial bacteria to colonize the tank and filter. These bacteria will break down wastes (ammonia, nitrites and nitrates) which are toxic to fish.

My fish tank LED light broke. Is using an LED flashlight safe for the fish?
Hello, and thanks for contacting Boop by Petco. Yes, the light itself is safe as long as 1) you secure the flashlight in such a way that you can be 100% certain it cannot fall into the tank, and 2) the flashlight doesn't create excessive heat.
