Fish Crazy
My rummynose tetra has been closely following a neon tetra (might be female) could it be trying to mate with the neon?
Well i have 6 neons and 1 rummynose so. . .How many do you have of each. If either species is kept in a group of less than about 6 of it's own kind, they will harass and try to school with other fish.
