i acclimated for 2-3 hours, i dont think its my parameters as much, because my other fish are fine, and i have no algae, the starfish and crab i added the same day are doing excellent and its not a new tank, the tank has been set up for almost 3 years, but i do believe its the other fish the tank, mainly my tomato clown..
the tomato clown was the first fish in the tank when i set it up, and she is quite aggressive, she has bullied and killed other fish i've tried to put in, i put in 5 chromi at the beginning of the summer, and when i noticed them coming up missing one by one, i started watching my tank for awhile, and noticed the tomato being very aggressive, and i saw frayed fins, but now i only have one chromis left and they get along fine..
i wasnt too worried about putting the foxface in tho, b/c the foxface is twice the clown's size, and i was watching the tank yesterday and didnt see the tomato chase the foxface at all...
