mine do this really weird thing after chasing each other, they rub bellies... it's very odd. i'm not sure if it's mating either but i haven't seen any eggs and such.
It is unlikely that they are preparing to spawn as Neons typically need strongly
acidified water with subdued lighting.
Sexing is somewhat diificult without experience. Females generally seem to
be more rounder bodied than males. Females may also develop a blue
longitudinal stripe which curves over more than the males. Unless they are in
breeding condition this is hard to tell.
Breeding in the communtiy aquarium would most likely end up unsuccessfully.
Instead move the pair to 45cm/18" tank. Use rainwater or RO water, and to
reach the desired Ph you must add peat. Aim for a Ph range of 5.5-6.5,
Breeders have found better results invery dark surroundings, they even go
to the extent of covering the sides of theglass with towels! Fish farms cover
them completely with no light. Neons are egg scaterers so provide either wooly
mops at the bottom or a plant with feathery leaves such as Cabomba. Condition
the pair before with live foods such as Daphnia and newly hatched brine shrimp.
Set the temperature to 24-26C/75-79F. If conditions are correct they should start
spawning right away. A good spawn could produce a brood of about 150 eggs. Once
the pair have finished you must move them to another aquarium with matching water
chemistry immediately as they are egg eaters.
At this stage it is vital that the eggs are not exposed to too much sunlight. The day
after spawning the eggs should hatch. After a further 3-6 days they should have
finished their yolk sacs and become free swimming. Feed them on cultured infusoria
or even liquid fry food. After a week they should be large enough to accept newly
hatched brineshrimp. Carry out partial water changes of about 25% every other day
at this crucial stage. If you folow this the fry will grow quickly and in roughly 12
weeks they should be sexable. At this stage move them to a larger tank of about
90cm/36in for growing on.
Hope this helps,
Mike

hi
as said female neons have rounder bellies and this makes their stripe appear to bend upwards towards their tail if you look at them from the side, if you have males & females it is relatively easy to spot the difference if you look carefully. neons will also chase eachother out of their own little 'patch' of the tank even though when they are frightened or the lights go out they will still gather together in a little shoal. so they could just be having little scraps rather than spawning. we see the same behaviour in our cardinal tetras.
