so a few weeks ago i bought a blusher angel and a few other small angel fish, when feeding for the first time i noticed that the blusher didn't eat much food only one or two flakes. i finaly got more freeze dried blood worms and she's oly eating those but now that shes eating the other angels (who are now bigger than her) keep trying to chase her off, i have no other tanks other than my twenty which is fully stocked and has a full grown silver in it, so my question what should i do?
