I have a 70 gallon tank. Lots of room and lots of hiding places. My 3 spot seems to be trying to mate with my female dwarf gourami? He chases her but not aggressively. He gets close but doesn't nip at her. Sometimes she'll let him hang out next to her for about 20 seconds before she takes off. He's young and not much bigger than the dwarf. Any ideas what's going on here? Are they just friends or friends with benefits?
