i have my female normal that had gone 5 months without feeding....it stop feeding around the beginning of december & just yesterday ate once again for me after 5 long miserable months... A guy well known here (Big Gunns) suggested to just offer food once in a while and they will eat whenever they feel like it...well thats what i exactly did & finally ate...& she is in a 60 gallon tank which is 4 feet long...i think you should just let it be & eventually it will eat once again.
