## Questions & Answers

**Q: want to get these for Congo tetras they're listed as having a Carnivore diet, is this high enough in meat based product?**
A: They do well for most all fish and are high in good nutrients. I personally use about 3 different foods and rotate them since it most mimics the wild .

**Q: Why is there sugar in it?**
A: It's a bad product that isn't returnable.  Strongly suggest you look elsewhere

**Q: Will this work for betta fish?**
A: YES! They love these Tabs. I have not had one Betta or other Fish not love it. Very good product.  😊

**Q: Can you break these in half and still stick them to the side of your tank or will they fall off?**
A: Sure can.  They do seem to fall apart more easily once halved, but I regularly half or quarter a tab & still stick it.  They also make a great sinking food for bottom feeders like Corydoras & can be crumbled small for top feeding fry.  Hands down may favorite feed.  Don’t hesitate, just buy them!!

### ⭐⭐⭐⭐⭐ Works well

### ⭐⭐⭐⭐⭐ Delicious treat for your fish!
*by M***. on June 23, 2026*

Everyone wants to eat these! I stick them on the glass for tetras, platties, guppies, white cloud mountain minnows, Endlers and rasboras. I drop them down to the bottom for the corydoras.

### ⭐⭐⭐⭐⭐ THE MOST RECENT FORMULATION IS A HUGE IMPROVEMENT
*by A***S on April 21, 2022*

When Sera originally reformulated the tablets I completely stopped using them. They disintegrated into the water and had a significant negative impact on water quality. I tried them again because I use their stick-on-glass feature to inspect my fish that are in quarantine and this is almost as good as the OG formula. It still comes apart fairly easily but the fish are enticed and the water stays fairly clear. I'm so glad that it's improved because now I can easily inspect my quarantines without having to net them.
