what are the tips and tricks to getting apisto's to spawn?? im pretty sure i have a pair, but don't seem to show any interest with each other. they don't chase each other away, and they look like a male and a female... but they have been in my tank for about a month now and have not done too much... ph is 7.0 temp is like 80-82. they have lots of hiding places & lots of plants. let me know what im doing wrong.
