ing Angelfish & Zebra Loach Question?

From what I have read it is hard for even the most experience angel breeder to an angel while young. If you had multiples you could go by the size but even that's not entirely reliable. It looks like only time will tell. Btw angelfish can be quite territorial in my experience but I'm sure you know that. Maybe adding a couple more zebras will help I have always heard they thrive in a shoal.
