almost yanked my hair out today. i thought id do my fast growing male motoro a favor n pump him into the 150gal now since hes getting feisty in the lil 60gal hes been growing out in. he throws splashing tantrums whenever he's hungry or just bored. so i go to home depot, buy some nice play sand, rinse rinse rinse, put it all in the tank, everything settles, so i go net the motoro into a container, aclimate over a few hours, then eaze em in. everything looks cool, he never been in sand so he burry's him self. i figure he's cool so i take off with my friends. come home and i see a disc like object floatin around. yup, theres the motoro... i got angry, transfered it back to the 60, he floated around for a while, then tada, he's cool now. all within 10 hours.
