I have a wrasse that looks close to a surge just cant remember the name of it, anyway it has been chased around by my lunare wrasse who is a little bigger, now I havent seen it for 3 days and I have checked on the floor around and under the stand and its nowhere to be found, cant fit up my intake so where did it go. I have 2 - 1 1/4" return pipes coming into the tank could it swim that strongly up against the flow? A LFS owner said he might have gone down into the sand to hide from the other wrasse but for this long? Hate to tare the tank up to look for him, any ideas out there on this?
