aqurium advice

Hello, so a week ago I got two baby mini peacock bass (2 inches) and two baby parrot chiclids (2-3 inches). A week has passed and one of my chicla unfortunately died (believe from choking on a feeder). I currently feed my fish once a day on frozen bloodworms and shrimp and were able to get them...

I saw a pirate perch for sale somewhere. It is a small predator fish. It gets about 5 inches and I don’t really know how to keep one so if anyone knows anything about keeping them tell me
