easy to care for, easy to sell for goodish money? some ideas off the top of my balding head, pure bred endlers/rare types of bristle nose/tropheus cichlids/good strains of fancy goldfish, are but a few...but the thing is, its not just a case of whacking a few fish in a 6ft tank, hoping theyll breed, then selling em on...youll need specific breeding tanks/ rearing tanks/filters/constant water changes/heaters/air pumps/specialist foods/time n dedication...to be honest, youll be lucky to make a profit... deffo get rid of the red bellies! they've gotta be the most boring fish going! the only time they move is when its feeding time
or when there's a conveniant unguarded arm in biting distance...
