Just that, my black molly is staring at my heater non stop. The light isn't on, but he just started this an hour or so ago. What is going on!?!?!?!? Definitely a new behavior for him
lol. funny you brought this up. I have a chinese banded shark that has been doing the EXACT same thing. he does it all week long. idk, i guess its harmless, wierd, but harmless.
