Thanks for the update! It’s great to hear that Big Bertha responded so well to the treatments and is now back to her old self again. You did a fine job of nursing her through this incident, Julie, and it sounds like there was a happy reunion when she was finally able to return to the main tank. Well done.
You can continue treating Julie using live adult brine shrimp that have been gutloaded with the Furan2 even now that she is back in the main tank with the rest of the herd, if you wish, as an added precaution.
Best wishes with all your fishes, Julie!
