So my puffer is about 4" long I got him July 5th of this year so probably about 3 or 4 months old. He is growing quickly. I have been feeding 1 cube of blood worms and 2 cubes of mysis shrimp. I have some dither fish in there that pick up scraps. I throw in a mystery snail once a week for his beak. I found a local bait shop that sells crayfish cheap so I was thinking I may start alternating them into the feeding scheduled. How many crayfish should I feed a day or week? I was thinking instead of frozen food tonight give 1 crayfish. he is still small about 4"
