Erupting abscess and blood in fins

Recommended Posts

Hi all,

 

I have a betta that has an unusual condition I haven't seen before. About a month ago, a tumor-like abscess popped up very quickly on my fish's back. (interestingly, the pigment in the affected area turned a dark turquoise color before it happened) The skin split open and there was some blood. I immediately changed the water and started him on a round of melafix and it seemed to keep it clean at the very least. I've been doing 100% water changes on his unfiltered 2 gallon frequently and dosing with melafix for a while now, and it is not solving anything. He's lost the part of the dorsal fin near the abscess and the ends of his caudal fin have become pretty ragged, and showing red streaks for a few weeks- hopefully not septicemia.

 

He seems like he isn't in pain, so I was just going to let him go as long as he could with melafix and clean water, but the other night something interesting happened. I had been more lax about the melafix lately, and I found him in poor condition on his side. I gave him a large dose of melafix and he was absolutely fine in the morning- back to his very active, hungry self. It even looks like the abscess has subsided a bit. Maybe this is treatable with stronger medication? I don't want to buy a bunch of medications to experiment with, but if you know what's going on and what I can treat with, please let me know. He is not an old fish.

 

Here's a photo from today. Sorry, couldn't figure out how to upload:

Does he usually have fin rot on his tail, too? Or is all the rot/deterioration on him within the last three weeks? That looks a bit like the columnaris infections we have noted on one of my other betta boards, truth be told. The saddleback gray/rotting area and quickly deteriorating fins. I can't diagnose him for you, but I'd ditch the Melafix and just go with clean, warm water. Melafix seems to do more harm than good sometimes, especially on labyrinth fish.

What are your water params?

I just did a bunch of research on columnaris, and I think you're right. I always thought it killed fast and left a cottony film, but I guess there are several different strains I didn't know about! The tail rot appeared 2 weeks ago. I'm pretty sure I can see some tiny rib bones there are exposed in the lesion :(

 

Params:

80*F

Ammonia- 0

Nitrite- 0

Nitrate- 0

pH- 8.1

 

I read that gradually lowering temps can lower reproduction rate of the bacteria, but I can't get the temp below 80 because that's just what our house is at, sometimes higher. I want to try a salt bath, and putting him back into a completely disinfected tank. What % do you recommend for bettas with columnaris? I'd rather treat on the aggressive than cautious side.

Ha. It looks like I might be dealing with it, myself. Salt helps stop the spread of it, but doesn't cure severe cases. It is a gram negative bacteria, so something like Kanaplex, Furan-2, or even Acriflavine should help with more severe cases. I'm doing Quick Cure, Kanaplex, and lowered temp for my Goldie, since I'm not positive I'm not also dealing with protozoan issues.

I'm no expert, you may want to message the mods who might not see this forum and get their opinion.

Where did you find these meds? What are the brand names? I only had a few minutes to look yesterday before they closed, but they didn't seem to have anything helpful.

 

Hope your fish feel better, too!
