I don't get algae growing on the glass or decorations because I keep it out of direct sunlight. There's a light in the lid of the tank which is on for between 10 & 12 hours a day, making sure the fish get a good balance of light and darkness. I've done my research

Here's a couple of pics:



Apologies for the quality. I'm using my phone to take the pics.
