Yesterday I was watching him swim around the tank and the emerald crab was sitting out out the rock. The fish swam by him and he reached up very fast, grabbed him and went under the Live Rock! I haven't saw the Clown since!
The emerald is rather large, probably around 2" across and he is in my 24g nanocube. He was tiny when I bought him. Has he out grown the tank and thats why he is aggressive or is this normal behavior. I will try to get a pic of him, maybe he just looks like an emerald crab but could be a different kind of crab? I have even been giving him food to try to prevent him from attacking the fish but I guess I didnt succeed. Please tell me how I can get him out of my tank QIUCK! I dont want to loose any more livestock! Thanks in advance
