today was the end of my cyle (4 weeks) so i decided to get a new fish and when i went to my lfs they were waiting for the truck to come for new fish so i did the same and i got a electric blue to go with my 2 electric yellows and powder blue but when i introduced him the powder blue got him runnin like a track star! he stays in the top and looks scared. hes about the same size as all three so thats not a problem. is it the stress from the shipping? does he need time to settle in? i will have pics tumaro.
