I have a. mandarin that’s currently eating copepods and brine shrimp, nothing wrong so far, except i want to train it to eat mysis shrimp and my rockwork is very extensive… when i say extensive i mean 2/3 of my tank is rockwork. any advice on how to catch the bugger? i have a mantis shrimp tramp with bbs for bait but i think all the bbs swam out alrdy overnight…
