I have just purchased a second hand 150L (~40Gal) and with it I inherited a few fish. I managed to take the trouble making red tailed shark and Kribensis cichlid to the tank at work but I am left with a beautiful male pearl gourami.

My problem is I already have a male red dwarf gourami and I am worried they wont get along. I was told that they should be fine if I plant the tank well enough and and if I gave them each a female to keep them occupied they may be less aggressive to each other.

Any advice or opinions on the matter would be great!
