Very pretty fish. With good food they grow really fast. Mine went from quarter sized to 6" in less than a year. But I did put in a small school of platies so she always had live food available..... they are quite the hunters
Just a small suggestion... Try s bit of flake every other day. It's a nice change to their diet and gives them things bloodworms and brine shrimp don't. (spirulina, etc)
