My mannish betta fish ?
Answers:    a 55+ gallon container and anything that wont fight with it (no large cichlid etc) or be swollowed unbroken (neons guppies etc)

they are very passive shy fish that make righteous additions to larger fish community tanks

things like congo tetras, giant danios, tiger barbs, rams/kribs, larger tetras, clown loaches, and even unresponsive larger cichlids like geophagus, angels, and severums

as for feeding, some may need to be enticed near a few live shrimp, but in short time should be eating frozen krill bloodworms and chopped seafood
What other on a daily basis or every other hours of daylight supplement that I can nurture my frog?   Can you use Sera Water Conditioner when the fish is contained by the cistern?   I enjoy lately set up a unmarked cistern relieve please.?   Important question! please aid! ?
