My fish are stuck in a routine too.
When i wake up in the morning, as soon as i get out of bed all the fish are awake and swiming hard together in a bunch in one corner, ready for me to feed them
Also they all swim to the top when ever i open the lid, even if i have just fed them......
This is kinda a silly question but do you think that fish like certain routines? Routines like feeding at a certain time, certain ways you do water changes, feeding at a certain spot in the tank? etc.
There is no such thing as a silly question, just silly people!
I mix it up, differant foods, differant feeding and cleaning scheduals. They, the fish, seem to be more active and responsive to poeple aproaching the tank.
