Hello. We just moved Bobbi, our blue gourami into a new home. Went from 10g to 20g. Planted. The 2 diffences are we put a black background on the new aquarium and we added a small light. She pretty much hangs out down by the ferns 90% of the time. Comes out for food but seems to be staring into the black background most of the time. She used to be more social. Thoughts?
