agressive algae eater...

[gophert]

I was wondering if anyone could help me on something. I started a freshwater tank a few months ago and bought 3 hatchet fish and an algae eater. They have been fine for months, the water quality is good and they're healthy. However, recently (the last week) the algae eater has grown agressive. It has started attacking the hatchet fish. Fortunately none of been injured, but I'm concerned that it may harm them. Has anyone heard of an agressive algae eater???


Thanks!
