Since we had to replace our old aquarium because of defective seals - we immediately bought a bigger and next to new plants - a few new fish. - Including catfish and gold stripe armored catfish. They are very nice and agile. Thus, it remains so we needed a good feed that quickly sinks to the bottom, but does not dissolve very fast and clouding the water. Lo and behold, the catfish, but also the other fish (guppies, swordtails and Zebrasbärblinge) pounce on it. Not every food has been so fast and well received. Even fish are picky. I break the tablet in half again mostly to portion to. For being so much in the package that it is enough for a long time, or you can give still other hobbyists something. (Durability when buying 06/2014 to 04/2017)
Conclusion: Very good food tablets that can be portioned, fast sinking, slowly dissolve and taste all the fish. Ours are all super-safe and sound.
