This is one of the best and funniest fish I have seen. They are forever scurrying around looking for food. They wag their tails constantly when swimming which reminds you of a dog.

They are timid fish and they will play dead if they hear any noise or you approach them too quick. This is really apparent when the water hasn't been changed for a week. Although saying that all shyness goes away when its feeding time.

They like swimming on the back of my tank where the filter is on fast. I have been in stitches with laughter watching the three of them swim against the current in a line and then get pushed back.
