have been busy renovating house the last few months. i'm catching up on all the posts now. just inherited two large angels, koi and blush about 4-5 inches. both are veil. will they be okay with my seven assorted rainbows?they've hiding in one corner for two days, offered frozen blood worms and they ate some, but the rainbows are hogs. i had two angel before but one died. he swims aggressively and gets his share of food. he's about 3-4 inches, not a veil. will the two new ones be okay?
