Try t find a tiny one. Sometimes you can find them as small as 1 1/2". My kole tang is less than 2" itself.
Yeah, that was the plan. Although the smaller you go with tangs, the more ich magnets they are...
I was looking at putting a hole in there, but I've never seen one that small. They are my favorite fish.
What about a henochius? They're active, bright and more suited to this size tank.
