I like to stack all my wood and stones in one pile, allowing more open space and smaller fish to seek refuge.
But it looks nice as is, but if you're bored, I'd weigh the needs of your boredom compared to your fish's comfort.
Dont know why i feel the need to reply to this,but i have been raising large fish for over 15 years(what good is hiding space for small fish when they are only large fish in the tank).
larger tank do you even know what size tank that is?(plenty of space for 4 fish)
and as far as the comfort of my fish,i take care of my fish very well(search all of my threads and see how many fish i have bred and raised over the years and the excellent health my fish are in)
not sure how long you have been keeping fish and you might even be an excellent fish keeper,i hope you enjoy this hobby for years to come and has your experience grow,you will learn that all species have different comfort requirments.
