These fish are also called Black Fin Sharks :dive:
 
I have two of these guys now. I got them when they were about 2" long 2yrs ago. They are now around 9.5" long! They can get a good bit bigger given right conditions. If you have a big tank without other fast moving fish, they are great. Mine like a salinity of around 1.008-1.012. I flucuate it every so often. I also keep the PH around 8.3. They are a bit of a nervous fish though. Don't crowd their tank with many plants or rocks. They like to dart very fast from one end to the other at times. They love beefheart and feeder fish. If you have any fish that might be too small, don't put them in there. These are a predatory fish. The little guy will be gone by morning.

i have 3 of the columbians about2-3.5inch long so far but only had them for just over a week unfornately i also have 4 zebra danois in the tank. while i was at school the danois had babies so a couple days later i have about 20 little guys swimming around so today while am getting a 5G tank set up i see my 3 columbians feasting on the little guys now i have 8 left including the 4 origonals so heres what im concered about will me sharks have a taste for meat and blood now and reject the flakes in a short time?
 
always swimming top right corner

i just bought two c/sharks from petsmart,
they are in a 45 gal tank with cichlids
the cichlids dont bother them at all... my question is why do the two new c/sharks swim at the top right? never going to the bottom?
any help will appreciated.
 
In proper housing (huge) they can grow to 18". They are schooling fish that prefer marine conditions as adults. They will eat anything htey can fit into their mouth.
