2 days ago my 3 piranhas which i planned to sell very soon due to tank size, killed one of the piranhas. so i took the 2 and sold them to a LPS for some credit. i didn't know what i wanted so i browsed the store and saw baby silver arros for $20. i jumped on it and brought it home. hes all by himself in my 29 gal and hes mostly chilling. hes just cruising at the top, all around the tank. the only problem is that i have not seen him eat yet. i put a little bit of food in each day. i have veggie flakes and live blood worms. i also have brine but idk if he will eat that. any suggestions on how to get him to eat? is this a common problem? any other foods?
