ok thanks guys! i already used almost all the rocks from the oscar tank in the new tank and some of the filter media also to jumpstart the process. i also warmed the water to like 85 to let the bacteria reproduce faster so i am doing all in my power that i can i just really dont want the little guy to die. i have had 2 and they did fine before but while they may not be rare for you guys, they never come around here. i had to special order my 2nd one and the first one was a random one at petco. what would be an absolute minimum for me to wait to put the ropefish in the new tank if i already did the filter media and new rocks? i did a small water change and used nutrafin cycle(all the lfs had) to try to help.
