I have been mass producing twin-fin goldbulbs,I know they are common ,I have them set at 30$ a peace . They sale reasonably well . I have researched evironments, marketing, and food . It seems it does no good , each time i buy the unusual eggs they all die , I have tryed breeding more delecate fish but they die also . What have i done wrong ? what do i need to get to make my fish live ? I also bought the heater and the aeration system . Nothing seems to keep them alive so I've just about give up trying to get new breeds and just make more money on the common fish I have already. Please will someone please tell me what has happen to my tanks ?
Thank you ,
Wings
