It’s so hard to know sometimes.
I was told on another site to do 100% water changes every day, but Russ here directed me to the 50% every 2 days with salt and rooibos tea (I couldn’t get almond leaves quickly).
And I’m so glad I did that.
Orion does not like change at all, though my other bettas have tolerated it better overall, he’ll ‘hide’ out for about 24 hours after any mild changes to his tank - even the air stone on for 5m seems to bother him.
100% wc would have wrecked him I think.
For all their oomph in personality they are fragile little creatures that can be affected by the smallest things. Each fish has taught me so much.
I really hope Indy pulls through. Again don’t worry about the food as much. They can go quite a while without.
