Okay, so I was skeptical at first because my betta fish was looking super lethargic after a move. Like, barely swimming, not eating – it was heartbreaking. Then I stumbled upon KOIKA BAC+ and decided to give it a shot.

First off, the smell? Yeah, it’s kinda funky (think butter popcorn mixed with... something farm-ish?), but my fish didn’t seem to mind. Within HOURS of adding a few drops to the tank, my betta started moving more. By the next day? Full-on zoomies like nothing ever happened. Miracle worker status!

I also noticed the water stayed crystal clear longer, which is a huge plus since I hate doing constant water changes. And my shrimp? They went from picky eaters to vacuum cleaners – they’re obsessed with their probiotic-laced food now.

Pro tip: Mix it with their food instead of dumping it straight into big tanks (unless you wanna waste product). Works like magic for fragile fish too!

The only con? My bottle arrived without a sprayer (ugh), but honestly? Worth it for how well it works. 10/10 would save dying fish again.
