Just saw this photo in my slideshow. Mr. Firemouth (Thorichthys meeki) was an interesting little fish. At one point, he shared a tank with an oscar (Astronotus ocellatus) twice his size, and ended up bullying the oscar all the time. Later, he had a little tank of his own and ended up hiding all the time. He was most comfortable sharing a planted tank with many smaller “dither” fish. This photo was taken shortly before he was given away.
