"2. there hard to keep together and they get aggressive"
Maroons that have paired up get along fine . If you buy two maroons that are not paired and from seperate tanks , they will fight . But can get along . I wish people would post from experience and not what someone else has said or posted .
"Not really, maroons get fairly large"
Adults get 2-3 inches , which is not large compared to some other clown species .
