I should explain. I have had a 72 gallon tank for about 4 years. I only have 45 lbs of rock. I ordered another 45 lbs. The existing rock is just sitting on the bottom of the tank right now and stacked. I want to make it more sculptured with caves and crevices for fish to establish their territories. We can see the fish right now but I think they are stressed out because they don't have that many places to hide. I can still add the PVC
pipes now, right? I just want to rearrange the tank and create a new home. I have a maroon clownfish, yellow tang, falcula butterfly, chocolate starfish and 4 snails. Should I remove the inhabitants to another tank while I aquascape? I don't want them stressing out.
Thank you everyone for your quick responses.
