My partner and I witnessed the first algae growth in Fluffys tank, we were so shocked that we changed the water immediately. When we were changing the water we noticed dark patches on the leaves of the Amazon Sword palnt, but they were washable. So what caused those dark patches?
Fluffy has become so used to his surroundings and he knows his feeding times because each time I go near his tank, he goes to the surface expecting his food. He has also been blowing a lot of bubbles, his bubbles make a thick ring on the surface.
I keep my room temperature constant because I realised that when he gets cold, he 'cuddles' against the leaves.
