I too have been into fish for 40 + years. At that time my large tank was a home made 50 gal. with oscars. I bred convicts and bettas in other tanks and had more fry than I could handle and no Internet to let people know. Today I have a 135 gal. that I have a small Texas cichlid and a small green terror that so far behave well. I would like to get into festae also.
