Wanted to share an update. I know it is past the 2 week guarantee but I hope you can offer some suggestions.
The laboutei was fine in the display the past 2 weeks. Sunday afternoon when the lights came on I noticed red streaks in his tail, ventral, dorsal and tail fin erosion and he wasn't using his tail hardly at all. I had noticed he seemed to drag his tail more than the other wrasses earlier but then would swim fine. So I watched him. Saw no stringy feces that would indicate internal parasites. Ate very well. This internal hemorraging and fin erosion happened almost overnight. Sat fine Sun had the problem.
I caught him and put him in my cycled QT. Red streaks often indicate bacterial infection. All I had on hand Sun was Melafix so I used it for a day. Yesterday went to my LFS and they had a marine penicillin based antibiotic. I put a pill in last night. Tonight I plan on grinding a pill up and mixing with small amount of vegetable oil to make a paste and mix with small pellets(got that from a marine disease manual) to get a dose into his system. BTW I know this may compromise the beneficial bacteria and I am prepared to do daily water changes to keep up the water quality.
I'm hoping your marine experts can tell me if this is an appropriate course to take. Or if this might not be bacterial but something else. When I checked him this morning I now see red splotches at his pec fins so it appears he is getting worse.
Thanks,
Phil
