any goldfish--esp. the ones with the bubble thing on their heads. they look ridiculous... also my common pleco gets on my last nerve--hes just a poop machine. Ill never buy one again.
I detest African cichlids....i could tollerate a female Frontosa they are fairly attractive but the males massive hump just doesnt do it for me. Im not a big fan of my P.natts either but they are kinda pretty in their own right. When they eventually kill over Im getting a Rhom. I hate Ropefish as well...eeekkk.
