Here are pics.. please help me identify.. I took him out and out of the water it doesn't appear white nor are the growths hard in anyway (like that incurable cauliflower thing)...

I have him isolated in a tank with a UV Sterilizer and am trying to figure out what exactly this is.. if it's fungal or bacterial... please help me so I can get the proper treatment ASAP.. :nilly::nilly::nilly:

He is not breathing heavy... he is rubbing a little bit.. this whitish thing on his top fin I thought was due to transport issues when i got him.. I've had him for around 3 weeks and it seems like it spread recently quickly to his entire top fin area only...
 
Like to also note he is eating very healthfully

And my water parameters are pristine...

0amm 0nit 10-20 nitrate.... two 50% WC's every week... Temp of tank around 82-84
 
He also seems to have a reddish tint around his vent area and fins... not noticing any worms though... so strange because his behavior is completely normal and has been for the weeks I have had him..
 
just noticed a "saddle shaped" dark spot around his vent area as well... looking more and more like Columnaris
 
I thought that saddle shape came on the dorsal region? I hope its not what you think it is. You will need levamisole
 
The white polyps are spreading to his body.. Going to treat with maracyn
 
I never see that before but put more salt in there hope he will get better
 
I wouldn't go crazy with the meds before you get a precise diagnostic, adding unnecessary stress (I personally never seen this condition before) ....I would just keep the water pristine , high temps , add salt and plenty of aeration . Hopefully someone more experienced in health issues, like Lupin, will be able to lead you in the right direction as far as medication goes.
 
Do NOT elevate the temp! This is definitely bacterial. Columnaris is most likely. Unfortunately, that bacteria is opportunistic and is always present in tanks. You can do series of water changes to reduce the bacteria count but salt will effectively repel it from latching on the damaged fins.

Transportation is always stressful to fish so it is not surprising your datnoid is succumbing itself to this type of infection. Mild infections require only salt (and no high temp; keep temp consistently at least 78 degrees to control the spreading of infection). Advanced stages require antibiotics (Maracyn Plus, a combination of Maracyn and Maracyn 2, tetracycline - more effective at acidic pH, kanamycin - more effective at alkaline pH, or Jungle Fungus Clear). Broad spectrum antibiotics must always be used as columnaris is gram-negative. Maracyn (erythromycin) works only for gram-positive bacterial infections.

Just as a warning, all antibiotics can disrupt biological filtration. And as with fungal infections, only Maroxy (look its active ingredient) can help curb it completely. Fungal infections are extremely rare. Certainly not the case here.
