I’ve hit the point now where the care is basically the same. Feed once or twice a day, skip food on Sunday’s. Water changes once, sometimes twice a week. And I just sit and watch them.
In terms of behaviour, Homer is undisputed tank boss. The two smallest are at the bottom of the pecking order. But not really much aggression. They sleep in the caves at night - so sometimes I come in to feed them in the morning and it takes some time for them to wake up. But never a problem.
