id like to know that to probably takes alot of time but good post idea your 10G wit a oscar pleco midas and parrot must very very very very crowed i would worry about the tank before training your oscar! seriously get a bigger tank man the fish would not like that
you got to get them to let you pet them first. once they let you pet them at your leasure, then you can slowly train them to jump higher and higher for even pelletized foods. then you can get them to take other foods. worry about a bigger tank first. if you train the oscar now he might jump to his death (they dont like overcrowding).
