How long to expect my orino to get to 6" he is currently about 2.5-3 and he has to be at least 6" to go into my 210g. I feed him very heavily about 2 times a day (beefheart, mysis, plankton, krill, bloodworms, live guppies and feeders, tank is consistantly stocked with 30-60 ghost shrimp that get to clean up the excess food so when they are eaten I know they are full of nutrients.
