A red-tailed shark female and a red-tailed shark male.
why not
Ther is no apparent sexual dimorphism in Red Tailed Black Sharks.
its a predator
Yes , they can if you have a big tank.
Yes, but make sure that you have a biggen enough aquarium. :/
A fish is an animal therefore it can be classified as both.
its gonna die
That depends on what kind of shark it is, but in general nothing less than 180-200 gallons. For some sharks, you need at least 700 gallons!
If you have a red tailed black shark that is in a small aquarium but you now need a bigger one, you can buy a cheap one through Amazon's UK website. You will be able to find a 50-gallon tank for him to go in.
Hopefully, a red tailed hawk would not be kept captive. They need to be free with plenty of forest and meadows to hunt in.
I wouldn't recommend it - since the RES will view the fish as food !
Well what else? The blacktip reef shark. What else? Spinner shark
