lol this tank here was supposed to be for breeding purposes only but then my shark out grew the other tank. all the babies i get are sold to stores i only keep the ones i really love so i can bred them to get the strain. too bad this can't be my job
Well... that's not true. You just have to change the type of fish you breed to trout or the like and you have to get a job at a forest preserve or the like where people go fishing.
Just get into more complicated fish and soon you should be able to easily figure out how to keep a wide variety of fry and fish alive and in good breeding condition. Good luck.
