Diadema Concern

[tatoush]

Hi all,
I recently added a diadema pseudochromis to my tank and at first it was showing the classic signs of being timid and cute....but not it is a pain in my a@#. I lost a shrimp last week, now I am convinced that it probably attacked it, and the other peppermint that I have is in hiding. He is flat out picking on my twin spot signal goby aka 4 wheel drive goby and forcing it either into hiding or to the front of the tank. Now since this is a nano tank I know room is tight.....I have tried to rearrange the rockwork to see if that would work, but no. Last night I put up a screen divider, but this morning I saw that my goby was not on the other side, so the pseudo must have found his way in and chased it into hiding. I also noticed that a he prob has been nippin at the goby's top fins. could use some advice, I really like the personality of the goby and am ready to throw the psudo in my larger tank so that he can get a taste of his medicine.... Any help would be appreciated

put the dotty back in the larger tank, mine was EXTREAMLY mean to everything when i put it in my 55 gallon with a CB angle, 2 false perc clowns, a scooter blenny, and a YWG, he even killled 2 pep. shrimp, and he ate a unknown crab, yours will probley start killing soon unless you put it in with larger fish
