Fungal or parasite infection?

[BettaSnap456]

My betta Tai has holes in his tail fin... I noticed that the holes had yucky yellow bordering on it.... I wish I could do pics but my cam sucks :/ Like the holes have yellow on it.

5gal
76 degrees
power filter and heater

I just put him in his new tank today...

[Sakura8]

Are there any other unusual characteristics? Do the holes have fuzzy stuff? Any black along with the yellow? What color is Tai?

Hello! I'm sorry Tai isn't doing well, but let's see what we can do. Please try your darndest for any picture, but its understandable if the camera really can't do anything for us. I see you've put some details about your fish on here already, but could you answer any more questions so that someone else could help you other than myself? I'm not entirely sure on this, but I can help you get started to get some real answers.

Housing
What size is your tank?
What temperature is your tank?
Does your tank have a filter?
Does your tank have an air stone or other type of aeration?
Is your tank heated?
What tank mates does your betta fish live with?

Food
What type of food do you feed your betta fish?
How often do you feed your betta fish?

Maintenance
How often do you perform a water change?
What percentage of the water do you change when you perform a water change?
What type of additives do you add to the water when you perform a water change?

Water Parameters:
Have you tested your water? If so, what are the following parameters?

Ammonia:
Nitrite:
Nitrate:
pH:
Hardness:
Alkalinity:

Symptoms and Treatment
How has your betta fish's appearance changed?
How has your betta fish's behavior changed?
When did you start noticing the symptoms?
Have you started treating your fish? If so, how?
Does your fish have any history of being ill?
How old is your fish (approximately)?

The water is kind of cold for one thing. What was in the new tank before? What is it made out of? What decorations are in the bowl- any plastic plants or something? Sometimes they create holes in the fin.... but for the yucky yellow... someone else will have to help you with that.

Good luck!

Tai is pink in the body and violet on his tail. No black on it.

I would increase your water changes to twice a week for a few weeks, just to keep the water extra clean. This will prevent the holes from getting infected. They sound like normal rips/tears for now but keep an eye on them. If at any time you see lots of black, post back because that could be a sign the holes are infected.

[BettaSnap456]

But, they're yellow, it doesn't sound like it's not infected.

[Sakura8]

I know, I understand what you mean. In mammals and humans, yellow is often a sign of infection. But not so much in fish. In fish, signs of infection are more black or red.

If you want, you can also add 1 tsp of aquarium salt per gallon to his tank, predissolved in a little tank water. This will help fight off any further infection. Don't keep him in the salt any longer than 10 days, 14 days absolute max. When you do a water change, redose only the amount of salt you took out. So if you take out a gallon, add 1 tsp back in. If you take out 2 gallons, add 2 tsps back in.

[BettaSnap456]

Alright. Thanks, will it go away with time?

[Sakura8]

Yes, I should think so. With clean water and the AQ salt, the holes should heal up and the yellow should go away. Keep an eye on it and post back if anything changes. Good luck, BettaSnap. :)
