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).
Unlike a purchased Billigprodukt they remain a long time on the ground.
They are usually so quickly cleaned away that they can not be resolved only.
Conclusion: Very good food tablets that can also be portioned, fast sinking, slowly dissolve and taste all the fish.
Ours are all super-safe and sound.
