Another set of gourami questions . Today I noticed the gouramis (2 opaline) weren't swimming around as much. They both have been hanging around the middle/bottom of the tank in/around hiding areas. They seem to be swimming around much less than before. Another strange thing is that about half of the time they stay still very close side by side (the smaller/agressive one usually doesn't let this happen and starts chasing the bigger one whenever theyre that close). It even seems like they're being 'friendly'. Occasionally the smaller one will give the bigger one a little nudge while perpendicular to it (big one seems to be ok with this). Another strange thing I noticed was that the agressive one has some small dark areas along the ridge of its bottom fin (looks like it may be nipping, but i watch the tank around 3/5 or the day and havent observed any). It also seems like the large one has lost some of its darker colours. I was curious, so I turned off the tank light a little earlier. Soon afte the lights were off the gouramis started swimming around more and the aggressive one went back to its regular territorial chasing routine. Any ideas as to what is going on here?
