closed BTA x 3 days

[likefish]

My BTA has recently decided to close up on me and is not opening...

No changes to the lights, water quality, feeding, temp......

Is this typical behavior? he has been happily hosting my new clowns for about a week and all has been well.

Any comments or experiance?

Now (and for the past 2 days):

mine did the same thing after it started hosting my maroon. Sometimes the they get aggravated by the clowns. They both get use to each other over time. Dont be suprised if it splits as well. Mine did about a month after hosting.
