Mental behaviour??
 

We have a yellow wrasse that has been generally very peaceful. This last week its behavior has been like a "rabid" beast. Not to the other fish but to us, as we peer into the tank it wants to attack us. In addition, the corals are also taking a beating by its constant flicking of large amounts of substrate that is landing on them. Can anyone explain this?

Some fish be crazy. That is all.


....Do you have more than one yellow wrasse in the tank?

Is it half tang? Cause all tangs are crazy lol
Is there a pair of them? Kinda sounds like spawning behavior not that I know anything about wrasse spawning but rather general fish spawning behavior.

Yes, i thought spawning or protecting its young (or eggs) but there is only one

i would go mental too if someone stuck me in a glass box as people peered in all the time and I couldn't escape.

Sounds like my office at work.... this could answer a lot of questions.
