D aruanus signal jumps

3 stripe humbug (dascylllus aruanus) "signal jumps" the fish makes these up and down movements and short bursts of pulses which sound a little like purring/croaking. not as loud as the aggressive calls, but the same basic sound component. The one near the front right ismaking the sound, but at least 2 othersin the background are also displaying. They don't always make the sound as they move.
