Glowlights Are Chasing

[JoanneH]

Can anyone tell me why my glowlights are chasing each other like mad? Its males chasing rather fat females, shooting all over the tank!!

Ive always had glowlight tetras and never seen any of them chase each other,they just hide in the plants and the decor and eat far far too much I had 25 of them in a 40gallon tank at 1 point and they still did the same.Yours may just be being territorial,i noticed mine used to bump into each oher so 1 of them moved to another spot
