LOL, Not the Aggressive saltwater hatchetfish!

But, tip for Identifying hatchetfish:
Silver hatchetfish: 3.5 inches, completely silver
Common hatchetfish: Silver with olive back and black line at the top of the body. 2.5 inches.
I accidentally got a silver hatchet. Although, the silver hatchetfish is almost like the leader of the school. I love when they get into a feeding frenzy. They all dart around at the surface of the water, fighting over food. They enjoy flakes, but they prefer betta pellets.
