I am new to sevs also. I got 2, maybe 3inch golds a couple weeks ago, & one is a total pecker. literally rushes at & pecks at the others' flank area. some scales look shaved off. I just want to flick him in the head. LOL. probably better off to add several at the same time & choose from them., my easiest source only had golds & I want a variety- not a bunch of the same color. so I'm looking for options. if the little pecker doesn't stop, he may be re-homed.
They're in a 180G with bigger geos & small dithers.
He is better when I hang greens to munch on, but they deteriorate quick.
