Red tail sharks and marble hatchets

[NFrons51]

I have 3 red tail sharks and 3 rainbow sharks, I saw hatchets online and thought a big school would look cool in the top portion of my tank but I'm not sure if there comparable with my sharks, any suggestions?

I wouldn't expect any issues between the sharks and the hatchets. I am impressed you don't have issues between the sharks however.

How old are the sharks?

 

[NFrons51]

They've all been in there for about 6 months, it's a big 75 gallon with plenty of caves and plants and I haven't had an aggression problem

When mine hit about a year old they started going after each other big time! Your tank has 10gals on what I had and you have more sharks than I did. So who knows maybe you'll be ok? I'd keep an eye on them just in case

You should really only keep 1 or 3 sharks. You are going to have many issues with those guys in the future..
