For the speculators of why BTA's have bubble tips sometimes.

[EmilyB]

I've had this BTA over a year, it was adopted from a 14w tank. It looked like a mushroom....

The anemone ended up in a 120 with 2 x 175w MH 10k, pair of maroon clowns. I think anyone who has visited will tell you it had long, straight tentacles.

A couple weeks ago, we took the sand bed out of the 120g (trigger induced), kept the anemone and the clowns in an established 10g tank overnite.

The 120g itself, ended up having a 70% or so waterchange. The water was well cured, and we really had no choice.

The BTA has ever since displayed bubbletips. Lights have not changed.
