hmmm. i know damsels are territorial, but for some reason, mine aren't. i have two yellow-tailed damsels, a 4-stripe damsel, and a domino damsel living in a 30 gallon tank. i bought them to cycle my tank when i first set it up over a year ago, but i didn't want to just take them back to the lfs. i kept them and they are getting along fine. i am waiting for them to die (mean, i know) so i can get some awesome fish instead. anyone know the life span of those little buggers???
sorry about your fish loss, lorna. sorry your chromis were so mean also.
