honestly, I think any fish out there that eats pods and other types of reef roach should be listed as a con-specific with the mandarin.
One of my goals with the new 115 is to try and get a pair of mandarin to spawn, and then see if I can rear the young... hopefully if they can be tank bread, they can be trained to take marine frozen 'staple' foods.
"Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words - "mank" and "ind". What do these words mean ? It's a mystery, and that's why so is mankind." ~ Jack Handey
