an aggressive molly??

[Twan013]

i've noticed a strange behavior since the addition of my blue damsel and lawnmower blenny (oh, and a hitchhiker molly lol).. i've had a medium sized molly, and a tiny one for a while... alright... that was just a background... anyway, now when i go to feed my fish (i use "aquarian" flake food in the blue container), the bigger molly constantly attacks the other 2 mollies for about 20 minutes after feeding them... i would think of the fish i have, the damsel would be the aggressive one... but he's just more "curious".. he'll follow a fish (not chase or nip or anything like that) until that fish goes into a crevice or hole... then the damsel would turn and go about his business... i think of it as "hey, where ya goin? oh, i don't wanna go there".... the bigger molly won't mess with the other fish, and i've never noticed him do this before... but now its like he tries to ram into the 2 smaller mollies... and like i've said, this only happens for about 20 minutes... my guess is that, even though the damsel isn't aggressive, he's still a heck of a lot faster, and he gobbles up the food in no time, not giving the molly a chance to get any, and the molly gets ticked and takes it out on the smaller fish.. also, i guess the dark green flakes are algae based or something, because the damsel will swim up to the green ones, look at them for a sec, turn around and suck up the white/yellow ones like there's nothing to it... that in itself is amazing to me.. how a fish like that can have a preferred taste... if anything, i figure he would "taste" the food, and then spit it back out... but not look at it and turn his nose up at it

By the term blue Damsel I hope this was not the one you put in there ? Chrysiptera cyanea They tend to get rather large and mean and never ever put a second on in there as they will mate and then own the entire tank..

i'm not sure what kind of damsel it is... its just blue, with a black dot, and white fins and tail... he's pretty small right now, probably 1.5"... seems to be doing well in my tank... when i first put him in, i noticed some of his tail was missing (nibbled off, pinched, whatever), but now he looks great, and its only been a couple of weeks! right now, he's probably my fav fish, keeps to himself, but as i said, curious, and i like watching him in his "bed" at night... he found a piece of liverock with a hole just big enough for him to fit in, and that's where he stays at when the lights are out...
