I wrote this to the seller
"I have many neon tetras of my own and I find it hard if not impossible to get a conversation going with them.
So what would is so different about this one!"
and he replied with
"Hi,
Nero the neon fish Is what we would call a spokesman for all neon fish. As he is a neon fish spokesman he is able to speak in many different languages, including Icelandic, French, Swedish, but manly English and Arabic. He is very quite when speaking but by dropping a stethoscope into the tank I can hear him clearly, just as if he was standing right next to me. He is very well spoken and has apparently lectured at many neon fish universities.
Thank you for your question.
