Sharks not suitable for any tank size.

[WILDER]

Id shark, any other fish not recommended for tank, as they grow far to big..

 

[MegTheFish]

Huh?
Are you asking what other fish aren't reccomended for the average tank? If so, redtailed catfish, koi, pacus, and common plecos are a few that come to mind.

 

[Dorkhedeos]

great white sharks, blue sharks, hammerheads. pretty much anything that is over 15 inches and is wide or tall

And saltwater.

Some loaches, eels, particularly moray and electric! Also yep, tiger sharks.... Oh my....really double check in some library books. There sure are fish out there that should never be sold for a tank life.

tell me about great whites... the guy at the lfs told me they grow as big as there tank! So i bought my nice little 10 gallon all included kit and got the shark to go with it immediatly.

well geese, after 3 weeks i had a fin sticking out and had to feed it 10 pounds of shrimp a week. it eventually jumped out of the tank and died on the floor!

Arapaima Gigas and Pangasianodon gigas

those fish look scary Mike...
I,m glad they don,t swim in rivers and lakes around here.... northern pikes and muskies is enough for me!
