Can we put a couple of 4" Pacu together with a couple of small Iridescent shark in a 150gl tank? Just curious

Another factor is id sharks are super skittish unless you have at least 6 of them together. So not even mentioning the size, they are anxious fish that spook over almost nothing. That in turn would cause a chain reaction. If you ask me that tank combo/size is a ticking time bombThanks. I do. Well, they are also very fast and strong swimmers. The pacus are nibblers too. Just afraid the tank would not be sufficient.
