Left this for my betta and 2 neon tetras, came home to the tank looking dirty where I dropped it

I bought this for my pet betta fish. I was going on a weeklong vacation and when I came back, he was dead. Bought another one two months later, went on a 4 day vacation again, and he also died. Don't buy this product, your betta fish will die!

Killed my fish, came back from vacation after 4 days and my brew fish was dead. Horrible product do not buy.

My first betta fish, Freddie Mercury, an adorable halfmoon-tail stars & stripes betta, died at age 2.5 years old a few days after using this product (Penn Plax PBV1 7-Day Vacation Fish Feeder) while I was out of town for a long weekend. I even go the one that says for betta. I assumed Freddie passed due to his age; he'd also had a tail injury awhile back. But ... I got my second betta fish, a beautiful platinum dragonscale plakat named Sebastian, and used one of these for a 3-day trip. Came home and within 2 days he was deceased. I'd only had him for a few weeks, and all water parameters, temperature, clarity, etc. were good, he was active as can be before I fed him one of these. I am devastated as I read these reviews because now I feel both their deaths could have been prevented. My pets are like my babies - yes, even my bettas - and I am so saddened that they did not get longer, healthier lives... seemingly because of this product. I don't think it's a coincidence based on timelines. With my beloved boy Freddie, I didn't realize it was the vacation feeder tablets. Now, after losing my sweetie Sebastian so quickly and unexpectedly, it almost has to be these pellets. No other discernable cause and I am heartbroken & feel sick over this. Shame on your Penn Plax (and Petco) for continuing to sell this, knowing that fish have apparently DIED!!!!!! PS: now, in hindsight, I wonder if some of Freddie's original fin rot issues began after using this awhile back too!

it killed my fish!!! do not buy:( it killed all my living plants as well

I was skeptical bc of mixed reviews. Returned from 7 day vacation to a happy, healthy fish! I did a 3 day test prior to leaving and thought I'd see stuff floating in the tank for the fish to eat but my hubby explained the tablet was dissolving and was releasing the nutrients the fish needed to be absorbed through his gills. So glad I didn't have to get a fish sitter or hassle to take fish on 8 hour car ride.

my fish was scared of it so he didn't eat it. Luckily I wasn't gone for that long so he was still alive when I got back.

Even after 4 full days it never dissolved. Then all it did was disintegrate. So my fish would have died if I relied on this.
