Fin rot On every Angel I have owned!!!

[rudyistaken]

Every angel I add to my tank seems to develop a strange fin wasting away symptom and eventually die. The fins will start to redden, and eventually start to fray and rot away. I always thought it was something in my tank picking on them until now.

I have tried to treat them, put them in a hospital tank, testing water parameters etc with no success.

My latest is a fairly large Emporer that has started to develop this symptom. As usual eats fine, and is actually in a 150 gallon with no other fish.

Is there anything else someone could point me to as the cause?

Could you please list every parameter you can test for: pH, calcium, alkalinity, ammonia, nitrite, nitrate, phosphate, salinity, temperature, etc.?

Steve, I am having a similar problem with a fairly new Lamarks angel. It has a bone exposed on the front of the dorsal fin it's gotten so bad. Do you think it could be malnutrician? The fish seems otherwise happy and eats like crazy. The water params are perfect in this tank. Is there anything I can do to help it?

 

[Steven Pro]

Do you have any pictures? Also, please list everything you cna test for and the numerical results.

Finally had time to take a picture. The bone that was visible sticking out from the front of the dorsal fin tissue deterioration has fallen off. The tissue is continuing to receed down the fin. I assumed it was malnutrician because the fish was picking at xenia and a brain coral. I have been feeding it frozen plankton but it does not seem to be helping.

Water Parameters:
Salinity 1.024
ammonia 0
Nitrite 0
Nitrate 0
DKH 9
Temp. 80

I have had 2 flagfin angels that died as a result of complications from fin rot. I cultured the fins of both fish, and they had a Pseudomonas bacterial infection. My tank pars are all perfect, and none of the other fish have ever shown any fin problems. I guess it is possible (if not likely) that different species have different susceptibilities to certain pathogens.

Saltyunderground: All angels and butterflies I have seen that on have had skin flukes. It has healed after I treated with Prazipro. I'm not 100% sure it was due to the flukes, but they all had it and they all healed after being treated.

Thanks LargeAngels.

I took a look at the thread. My fish has no problems with it's eyes and not white spots. The fish is active. Just the fin issue that I can see. It seems to be accelerating in it's recession the last two days.

They don't always show up on the eyes. They don't show all those symptoms. Some you see nothing on, some the torn fins, some redness, etc. About the only time you can actually see them is when they cover the eyes or when you do a FW dip.
