betta fin rot

[Indigo Betta]

he's still eating and active
and he's still getting holes that normally heal after about two days

he's had one quite big hole on the tip of his tail fin for a about a week now that doesn't seem to be healing

I don't think the myxazin has really done anything at all
the five day course ends tomorrow
so i'll be doing a 100% clean out and then putting stress coat in

Okay. If you can find a source of tannins that may help as well. Indian Almond Leaf or naturally dried oak leaves work. Rinse the leaves and crumble into the water to make it dark brown. You can also just place the leaf in the water but it takes a little longer for the tannins to seep out.

what does tannin do? is tannin safe for fish? i've got oak leaves in my garden.

[Sakura8]

Tannins have antibacterial and antiparasitic properties and also help to acidify the water and turn it dark colored. This simulates a betta's natural habitat which can help put the betta at ease. The tannins will help to combat infection.

okay i'll put a dried oak leaf in
how long should i leave it in for?

[LuckyBlue]

to the person who posted the links.... for the orange rescue fish

what did that person use? salt....? too many pages for me to read thru..

thanks much!

Indigo, you can leave it in until it gets so waterlogged it starts falling apart.

[Indigo Betta]

is one oak leaf enough for a 6 gallon tank or should i put more in?

[Sakura8]

One leaf should be fine but two leaves won't hurt. OFL says you can't overdose tannins.

[Indigo Betta]

he likes the oak leaves so much he built a bubble nest round them
unfortunately i have to clean the tank out and destroy his bubble nest though

I used the testing kit it and it said
ph is 6.8
nitrate 25
nitrite 0
ammonia 0
carbonate hardness 100
general hardness 250

that big hole on the tip of his tail fin that wasn't healing has now split down to the to the very end of his tail
