## 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!!

### ⭐⭐⭐⭐⭐ Fish want Sera O-Nips
*by M***H on July 28, 2019*

Crack for freshwater fish. The only foodstuff that even comes close in popularity amongst finicky eaters is mysis. It might take some fish a little time to figure out picking at a tablet stuck to the glass, but they all eventually figure it out as they follow the bits that float off. It would be nice if Sera would make these in a smaller tablet size for feeding lightly stocked tanks-- just another excuse for adding more fish! Tabs can be scored and split with a butter knife for feeding in smaller portions. I do so on a clean piece of paper so as to easily tip any small bits back into the original container for later feeding of nano fish--the powder remains are great for fry, or to immediately pour into a tank to chum up the waters. Broken portions of tabs can be tricky to stick to aquarium walls but it is possible. The trick is to press a finished/smooth flat edge firmly against the glass until there are no bubbles escaping. Fish just want to eat so they are fine with just chasing a tab around if adhering one to an aquarium wall is a bother. The contents are good, but not my first choice for maintenance feeding. Nutrition is not really the point here. These are a treat for pets that also entertain the pet owner. That they are made of good ingredients ( and piscine crack!) is just a bonus.
