Female Square Spot Anthias - Spawning

[gstar1]

Does anyone have experience with Square Spot Anthias spawning? I have 1 male and 3 females in my 125 gallon tank. One of the females has a larger belly then the other two and swims vertically and wiggles her tail rapidly and does not get along or swim with the other 2 females? Is she attempting to spawn with the male?

Sounds like a swim bladder problem/infection, definitely not spawning behavior.

Any thing I can do to treat this?
