So I'm just doing some research for my future aquarium. I really like the hatchetfish. But, I can't find certain information about them. It says they're schooling fish, but other places say small groups. What size is ideal? How big do they get? I've read up to 1.5 inches, and I've read all the way up to 3 inches. I'd prefer smaller, as I'm also going to have a school of glowlight tetras, and like everything to be generally the same size. I also want to get some cherry shrimp. Will they try to eat them? It's going to be a 100 gallon fully planted community tank.
