Thanks for the information :) That's really informative! I tried to group them for the sorority, properly, and she and Holly got into a scat. Ugh. TWO dominant gals.
Holly's missing a chunk of fin and the bigger gal Savannah is barely injured despite Holly attacking viciously. Neither will be in a sorority I guess!
Savannah is pretty healthy. I've had no problems with her, she was quarantined 2 weeks when I got her, and I did buy 2 fiesty young males (one JUST barely matches her size), who are pretty aggressive so we'll see come summertime :) I now have a 20 long, and a 40 coming soon here. Loads of space for grow out!
thansk everyone for the information :)
