My white skirt tetras aren't schooling together?

Your tank is too small : ) Not too small for them, but too Small for them to feel the need to be right next to one another.

They can see each other, and there's not a lot of space or other fish to fear. Schooling is more a defense mechanism, to protect themselves. They more than likely feel happy and complacent in your tank and don't feel the need to be right next to each other. They may later as they get more used to one another but I would;t expect them to school like they would in a big huge tank : )

Best of luck!

No. I have both in a 40 gallon and they do not school at all. Skirts do not school around in formation. They do interact with each other. Schooling in a tank is different than the wild. Smaller tetras, danios and others actually go around the tank in a group/formation. Larger ones like skirt, diamond, giant danios and others just interact, they just don't swim around in a group. My white and black skirts don't school but they do interact a little. They mainly play with their own color/species. I did noticed that the white skirts and Glo-tetras interact.

Tank is way too small. White skirts and a few other large bodied tetras are "loose schoolers" meaning they will hang around each other, but wont school like neons or cardinals.

In small tanks, youll never notice the schooling. In larger tanks, with more fish, you will see it all the time.

Ditto mwm the schooling has to do mostly with whether the fish feels scared or threatened by other fish-strength in numbers mentality.

And, ditto everyone else, your tank is too small for 8(?) skirted tetras.

Well a possible reason is there might not be other fish in the tank. Fish in the wild school together for safety. With no present danger, it might seem to them there is no need to school. I wouldn't worry about it for now. Give it sometime and you may see them schooling

It means there happy.....

these aren't timid fish.. If they sense no fear they they just putz around the tank at there Leisure.

Something spooks them and they will reform there school.

Only cardinals, rummy nosed and harlequins school almost 100% of the time. There really timid fish.

the rest really won't.

They won;t swim much because there isn't anything to do in such a small tank.

good luck

It's normal, don't worry.
