Help... Flame Angels Dying in QT

[nim6us]

My QT is 12"x12"x30", standard jager heater, HOB filter, MP10 wavemaker, thermometer, Seachem ammonia badge. It's got PVC tubes for hiding and some marine pure bioballs and I do a 30% bi-weekly water change.

I've run 4 rounds of fish through there, I do 2 fish at a time, all of them have lived aside from 2 flame angels. I just lost the second flame angel yesterday and it's really baffling me. I keep them in for 5 weeks, for just observation but don't treat with meds unless I have to, neither time I've had flame angels die have I treated with medication.

Both times the symptoms I see with the flame angels are their fins start to fray, and then maybe a week later one night they don't eat, the next day they're dead. I didn't record it the first time, but this last time I noticed the night he wasn't eating he went pale, almost white in the mid section. Breathing wasn't heavy, he wasn't laying on the bottom, he was just hid away in by the filter away from everything.

I had a coral beauty go through QT and he was fine, they're both dwarf angels so I don't know what I'm doing wrong. All the tank mates have been very peaceful, the first flame angel was with a goby, and this second time he was with a longnose hawkfish. Flame angels are one of my favorite fish but I can't buy a 3rd one until I figure out what's going wrong.

What would cause fraying of the fins, and then one night of stopping eating and the next day death?

Sounds to me like you are doing things right. My only comment is that I would sterilize between quarantines. Let’s see if someone else can help.

Fraying of the fins is usually due to a bacterial infection. The important thing to ponder is that these are usually a secondary problem caused by something else: like flukes, velvet, etc. Hiding away from the lights can be a symptom of velvet. Sometimes velvet kills very fast without the normal visible symptoms.

This is the second time I've heard it may be bacterial. Any recommendations for bacterial meds?

On hand i like to keep.

Metroplex
kanoplex
Neoplex
Furan-2
Tetracycline
Doxycycline
And ciprofloxacin

As an initial treatment for body bacterial infections i use a mixture of kanoplex, neoplex and furan-2.

Doxycycline can be used in emergencies if all you have is a big box store open. As most carry api fin and body. But has more side effects than the above mixture and can be very harsh on nitrifying bacteria.
