Curious as to if there is a certain food I can feed that will REALLY make my Jar grow? He is a piggy now and doesnt care to much for the taste of other fish so I feed Nite Crawlers, Meal Worms, Crickets, Krill, Plankton, BeefHeart, Blood Worms and gonna start Aro stix here soon. Also, what bout coloration? He is turning very Gold and he is getting spots on his tail... anything to enhance color?
