Bubble Nest

[smurfthebetta]

Hello,
May I know at what age does a betta start making bubble nests? I recently got a new betta fish which was claimed to be less than 3 months old, but he is already making nests.
Just curious

Usually as early as 4 months old.

Anywhere from 3 months onwards, depending on how well they are cared for.
