Will a Oscar or JD work in my tank?

[JAY ROB]

I just upgraded to a 75 gallon tank. I currently have a red finned cigar shark thats about 8-9" and one electric blue crayfish. I'm thinking about adding a Tiger Oscar or a Jack Dempsey. I saw a video on youtube that had an oscar with a red finned cigar shark. Any opinions?

Here is the video I'm referring too.

Might work just fine ,but you would wanna remove that crayfish.When big enough either fish would eat it.

the crayfish has gotten to be about 3-4 inches big and he has a nice little cave he stays in a majority of the time. the red finned cigar shark doesn't really mess with him.

I thought one of those big-enough-to-eat crawfish from the grocery store would be big enough to defend itself against a JD. My JD only ate pellets and refused live feeders. But the crawfish eventually only had no legs or antenna only the claws were left. It died shortly after. I think it was a territory thing, not so much him wanting to eat it.

The JD may work but an oscar will outgrow the 75.

The JD may work but an oscar will outgrow the 75.

75 should be ok for 1 Oscar. Its really the minimum anyone should ever go with a full grown Oscar.

sounds like a good excuse for me to upgrade from the 75 gallon tank. my fiancee will just be thrilled! lol.
