I have a question as well are there 2 fish labeled the ID shark? The ones I see now are striped but what used to be around here labeled ID shark was a shiny blue/black with a white belly and throat. Are these the same fish or not body structure and face look the same but colors are different. It was mentioned as well that ID's are quite predatory to small fish.
Amber n the boss what do your Ids look like as far as color?
I have read they are jumpers and of course flighty. The one we have in a 160 is calm as long as there are no nets in the tank. He is in with some CA cichlids and is doing well and eats sinking pellets right along side of them. Your a least have 2 together which I have read relaxes them a little as they are a schooling fish.
I hope this thread goes on for awhile as I too would like to learn a little more about them.
