i jus bought a dolphin shark, an my re tail is goin crazy now, its tryin to attack every single fish! my mother said she saw it the other day goin for my silver shark, so i phoned the pet shop and they said it the dolhin shark cudn't live with any other fish and the red tail shud b swapped in...

this don't make sense becos when i asked i was told dolphin sharks r ok with other fish !
