Spotted Mandarin...eatings but getting skinny....

[Cameron]

I have had my spotted mandaring for over 2 years. He has been eating mysis for years. I had him in my 45gal long, with rocks, and sand bed, in Victoria.

I moved to Abbotsford, moved all live stock into a 250RedSeaMax, he is eating mysis again but I have gone to bare bottom.


Could moving to the bare bottom be starving him, not sure how he is still eating mysis.....Should I go back to a sand bed????
