Is my BTA unhealthy?(pic)

[Mikro]

My BTA has lost the bubble tips and are just stringy.
What might cause this ?

Unfortunately its normal in the home aquariam for them to go stringy.
You will usually see bubbles in the early morning or late evening but the rest of the day they stay that way.
No one knows exactly why.

You're BTA looks very healthy. Bubble tips are not a sign of health.... Your's looks happy and healthy
