They are, you rarely even see them flare.
I took a pair to show and they got first place. I took them home and put the pair back in the grow out, it was funny how they strutted around like "We got to go bye-bye's,neener neener" As crazy as it seems, the entire tank seems to trust me more after that. Maybe they know,now, that I'm not going to cause them harm.
ooops, one more story! Last week I was doing a change and talking on the phone (not a good combo) left their tank draining and it was literally drained a good 8" to clear the top. I wandered back in maybe 15 minutes later and one was on the floor, covered in fuzz and on the dry side. I put him in a cup with silver,left him for a few hours. When I returned he was looking a lot better so I dumped him back in the tank. He fell to the bottom like "whew" and a sibling came over and laid beside him. It was so sweet. A splenden wouldn't have handled the situation the same way! No way!
He was fine by the way. I don't even know which one it was now.
