They were so pathetic looking when I first got them. All the females had nipped tails and were so skinny compared to my original trio. Now with lots of cover, daily feeds of live and pelleted food, they are plump and healthy. They will attack your hand if you put it in the tank and zoom over as soon as they see you. Definitely one of my friendliest killifish species.
I also see them spawning all the time, but one of my sparkling gouramis was swimming around with an egg in its mouth the other day, so I think they have been eating them.
