Purple algae?

    In the past week a red/purple colour has formed on the bamboo I have in my tank. It's only on a few of the sticks. There is also little black dots on it. Any ideas what it is? Dangerous?

    Is the leafy part out of the water? If not it can cause them to mold. I would move them out of your tank temporarily.

    They're not actually live. Their just dried bamboo with weights on them

    Hmm. Perhaps a bacteria bloom even though its not live? (Similar to growths on driftwood?) not sure about purple though. Bump

    It probably is bacterial. They're likely feeding on the rotting fibres in the bamboo.

    It is definitely rotting or something is feeding off of it. I had a dried bamboo stick in a betta tank once and the same thing happened after it was in there long enough. I would definitely remove to prevent it from spreading.:;soldier
