yeah you have to be so careful on background choices coz they can look real tacky but when done right look great its good your takeing your time o find the right one
those sharks get quite big and nasty. in my experience, the red tailed sharks are slightly more aggressive than the rainbow shark.
i feel you only have enough space for one when it's fully grown considering terratory etc.
alot of lfs's are selling sharks in there threes these days, it's wrong! lol
they may be fine at the moment but once they reach the age where they want their own terratory, you'll most probably have 2 dead sharks considering the mixing of the species. soz dude
