Well im sorry to say but thats not even a bichir so why theyre calling that a dinosaur eel i really dont know.
That is a dragon goby, scientific name Gobioides broussonetii. They are peaceful filter feeders that can be combined with even small fish. They grow to around 15" normally and need a sand substrate as they like to burrow and will sift it through their gills to find tiny particals of food. In a community tank they can be difficult to feed and many animals starve, they will need small live "pond" foods like daphnia (water fleas) and bloodworms which need to be placed close to the fish so they can find them easliy, dragon gobies have very poor eyesight and find their food with their good sence of smell.
