I agree with King on WC's (I would do 20% once a day), bump temp to 84-86* (make sure the water is well aerated) and would add aquarium salt. I wouldnt feed him more than once a week as Bichirs can go a little while with out food
The tank you moved him too, just make sure u are using a cycled filter
