Ok, so my roommate recently had a tank given to him. Neither one of us had ever owned an aquarium before and we made some obvious newbie mistakes. I have done a ton of reading since then and have become quite fascinated with the hobby. So I have a few basic questions. First of all, we learned about cycling the tank the hard way, and have now pretty much locked ourselves into a fishy cycle. So just had the water tested a few days ago and the amonia was between 4 and 6 so it is coming along properly (i think). My roommate originally bought 4 fish, of which only the Plec is left. On top of having to deal with the cycling, another newbie mistake my roomy made was purchasing his fish from Wal-mart. So this poor guy is covered in Ich. He seems to be very tough and has outlasted the other fish that were bought with him by several days. A few days later we added a handfull of goldfish for the cycling. So I would like to try to increase his chances of surviving the cycle and was wondering A) if we should be doing water changes during the cycle (if so could someone please give me at least a somewhat detailed description of doing a water change or point me to one). B) can we treat for the Ich during cycling? Because I was thinking about doing a salt bath that I read about and I have already turned up the heater in hopes of bringing the temp up closer to 80. I really have more questions but I want to keep this post to a readable length so I will ask those later in this thread or start another. Thanks in advance for any and all help it is greatly appreciated. This site has already provided me with a wealth of information and it is definately appreciated.
