Sand.do i need a special type of substrate for him?
I hope this is what happened, 'cuz otherwise he's most likely a goner as he probably won't be able to pass it. Which is why sand or bare bottoms are recommended for polypterus of any type. Some will swallow a piece of gravel and be unable to pass it, and literally die from constipation. It would most likely be an incredibly painful death, too.phillydog1958;3622998; said:how do you know he actually swallowed it? i saw mine attempt to eat a piece. he chomped down on it a couple of times and spat it out, after realizing that it was not food. maybe your's did the same and you just did not see him release it.
