so i have a 100g tank on the way..and im getting a bichir for it.now, today i was at petsmart checking them out..they are labeled "dinosaur bichirs"...after doing a google search it seems like this is just a common name they use for a bichir in general.now im sure you have all gone to petsmart...they have the little baby greyish ones on a regular basis. i know ornates and all that good stuff and these do not look like them.is a dinosaur bichir a specific species or do they just not know wat type they are?
