Should i use gravel about a third of a cm big for a 6 cm big axolotl?

should i use gravel about a third of a cm big for a 6 cm big axolotl? (which i got today)

id say he could still snack on it, and it would block him up at that size probably but adults might not. do you have any finer stuff around?

I would say omit the gravel for now, just go without any substrate. If the gravel is really that small, it might be OK for a larger axie. But even for a larger axie, you should probably feed it out of a dish or in an area without the gravel just to be on the safe side.

thank you he/she seems to see if it nkows that it isnt edible or something cus its got some little grains of food around the pebbles and hasnt even tried to eat them
