so the tank is about 4 months
tank is 75
gal with 90 lbs of
LR
i also have a yellow tang, clown fish, 4 blue chromis, purple dottyback, algea blenny, a chalk bass, coral banded shrimp, RBTA, pulsing xenia, and about 100 obselta snails,
my tiny hippo blue tang, 1 inch, is not doing her normal activities today. when i got home, my wife said "Dory" has been hiding and looks scared. The tang has been resting or sleeping every night in the same live rock hole, but today, most of the day, she has been in the rock. Every so often, she will come out and swin around but she looks fragile or scared, and weak swimming against the currents of the power heads. When i fed the tank today, she did not come out to eat but maybe once and got a tiny piece. currently as im writing this msg, she is actively around the rocks, but not as usual, and swims weakly. Mainly she swims with the clown fish, all over the tank. She is about 2 weeks old. i meant i put her in my tank two weeks ago after purchase from
LFS
in the two weeks i had her, she has been very active, feeding frozen mysis shrimp, flake food, and seaweed
What can i do or look for?
