Wrasse behavior

[trickyy21]

I've had my six line for eh, id say almost 3 months now and hes been doing just fine..but recelntly has started to display some strange behavior..as he is darting along he will sometime flip flop back and foth onto each of his sides, probably about 4 or 5 times and then go on swimming normally. Ive only caught him doing this two or three times but its a bit concerning....anyone know whats up?

I have a yellow "coris" wrasse that is doing something similiar to what you have described. He does not look stressed or anything to that extent, but I wonder as well what it could be.

Where are you getting the water for your water changes? How are you treating it?

Depends what i have time for, sometimes i will use r/o water, other times ill use regular tap water and treat it with Prime

My guess is that something in your tap water is bothering him.
