I want really cool fish?

If you get one, feed piranhas they are gay fish, i hate pheranahssss, cuz there mean, the day i see pirahnas eat a clown fish, is the day ill cry for fish...

There are five categories i can think off the top of my Head,

Tropical - I keep tropical there great to watch and a very large very cheap category. (includes Discs, Plecos and angel fish)

Marine - These fish are amazing to keep and an excellent choice but if you are new to keeping fish i do not recommend these because of there price and there high maintenance.

Cichlids - Dont know alot about any of these fish but do know they look awsome.

Ans like coi carp (you keep them outside) - Great garden fish can live up to about 20 years you can get them cheap young then sell them for about £150 When they are full grown.

Goldfish - Good old goldfish not the most exiting fish but great for kids and new comerers to the pet world.

Hope i have helped.
