as far as making them pair up, it depends on the type. Ocelaras will pair up if you jsut put them in a tank together when they are small and sexualy imature. moroons are more difficult. Please specify.
to make them spawn, it usualy jsut tanks time. They must be acclimated to their tank which could take months or even longer. But if you have been waiting forever and cannot wait longer, there are some ways such as raising temp to 82 degrees. leaving lights on for 14 hours a day. leaving your moonlight one, feeding live brine srhimp enriched with vitamins, any other live foods, feed them a more varried diet, large water change of up to 50%, have excellent water quality. add some phytoplankton to your tank without disturbing quater quality. jsut up the nutrient level.
and last but certainly not least, play barry white albums :dance2:
