one of my moms angels died and I am partly responsible. I want to make it up to her. She has always wanted a knife but feared to try in a communtity. There is a 2" creamy white albino featherback white pink eyes for $20. I don't know the variety. Would it be safe in moms tank? she is afraid it will eat the yoyo loach and the activity of the other loach will stress it. Is it compatible aggresion wise? Hunter wize? the store feeds it the smallest of feeder guppies and frozen brine shrimp.
