How did you fail? Did they lose interest or something?
Condition them with lots of frozen foods. If you only have access to one type of food, is OK (I mainly feed mine frozen bloodworms). Feed them until they bloat 2-3 times daily for a few weeks. Remember to keep up with water changes - the more you feed, the more water needs changing.
During the whole period, isolate both. Exercise them daily to the same sex.
Try using densely planted method (1/3 - half of tank). Use bushy leafed plants like cabomba or anacharis. A floating water lettuce is also good for the nest and the roots may house lots of micro organisms. Or use those soft plastic ropes (not sure what they are called in English). Tie the rope to an anchor then strip it into small threads. Use enough for the female to hide.
Make sure you know what swim flirting is - they must be in breeding mode. When you are 1001% sure they are in breeding mode, you could either put both in at once or put the male in first and the female the following day. Put them in just before dark - with no extra lighting. They should become less active at night but can sense each other (less damage on female). Let them be until they spawn. . . . if they are healthy, they will eventually spawn.
