Bala Shark

[George&Ade]

Hi,Over the past couple of days,ive noticed my Bala Shark develop sort of red streaks on all of its fins.
It doesnt seem to be too distressed by this,and is eating as normal.
The only thing different i have noticed is...he seems to be "twicthing"
He does it when he is stil and not swimming around.
All the water levels are perfect.....regular weekly water changes of about 15%...and temperature at a constant25/26 degrees.
I dont think its an emergency,but would be gratefull for any advice.....just in case.

It sounds like a fungal/bacterial disease called Hemorrhagic Septicemia--red streaks on fins or body with no sign of skin damage. There are medicines for it that can be bought for it in your local fish store.
