Please Everyone help me Identify my fish!

I am a new member here, and a new cichlid lover. I don't no how to post the pics of my fish on this but if you click the camera under my username you will see all my fish. Please help identify them. and what ones can be together because I no they all are not compatible.
Thanks

 

I can see a female convict and an Iridescent Shark(I think)...is there any fish missing for that shark to have such a big belly? the shark alone gets anywhere from 1-4 feet big...the others I'm not sure sorry

 

At the pet store it said it was a silver tip catfish. I found online that it is also called the Columbian Shark

 

ahhhhhh ok yes it does look more like the Columbian Shark still a big boy and very nice looking..although ive never seen such a big belly before !!

 

if it IS a columbian shark, then it can't be kept with the rest of those fish. columbian sharks are actually brackish when juvies and should be slowly switched to full marine as they grow into adults.

sorry I can't help with identifying anything, i'm not very familiar with cichlids
