Okay so I have a 29g and a 90G and want to merge the livestock and rock from the 29g into the 90g and I'm not sure how to do it. The 29 g has been up and running for about 2 years with no problems and the 90g has been up and running for 1 year with no problems. Should I start with moving the rocks/coral into the 90g slowly... like 1 every few days? I really want to keep the stress level of the fish to a min. The fish that will be moving from the 29g to the 90g are 2 clowns, 1 6 line, and 1 yellow watchman..oh and 1 skunk shrimp. I will need to get most rocks/corals out first because I don't think I will be able to catch the fish with them in there. Any ideas?
