Ghost shrimp in 40 gal.?

First : no those fish will not eat your ghost shrimp nor tag the frogs - they're very quick not to let themselves be harmed. All those kinds of fishies are too docile to attack ghost shrimp & frogs. Besides ghost shrimp are super yuck-cleaner-uppers! 2nd: Gouramis, angels, swordfish, danios, tetras, cories, some sharks.. any labeled "community" fish and buy enough of the mollies, danios, tetras & platies so they can school. Gouramis & angels can get up to 12" and live up to 10 yrs so buy ones you'll love to watch a long time.
