ive had my suncat for about 6 months or so and he has always acted the same as what everyone describes. when lights are on he is always hiding, darts out when i put food in, gets his and darts back to his spot. the last 2 weeks he has been very active swimming back and forth from one end to the other. the only change has been that i added a black arowana. water parameters are perfect. does anyone have a suncat that is normally active when the lights are on? im loving the fact that he is out cause he is gorgeous but am a little concerned that its due to stress.
