I just picked up a pair of juvenile blotched anthias and concerned that they may have bladder infection. i had a square anthias months ago in my QT and it was eating fine but it was swimming similar to these guys (see video). I am being told by the guy I purchased from that blotched anthias swim a bit strange. Let me know if I am crazy here . but seems strange to me for them to swim this way. They are both eating, but so did my square anthias but died after a month.
