alright, new question:
the larger of my two archer fish has been changing colors. well.. to be more exact his stripes are fading a little. he's still active and eating (and shooting) the tank parameters are all normal...
he's only 4" or so, so i'm assuming it's not mating behavior.. is it stress related maybe? we're in the process of moving.. is it possible he doesn't like the changes in surroundings (i.e. all the furniture around him and his tank has been replaced with boxes)
