My 2 clown fish used to swim through the little caves i made using the LR but since yesterday when i added 7 blue legged hermit crabs, the clownfish stopped swimming through the rocks (the hermits climbed them to clean). And now all my clownfish do is just swim above the rocks or swim up to the crabs and just stare at them. Could the clownfish be feeling uncomfortable with them crabs? or could they just be examining them:]
