Hello As a lot of you know, I have been battling Camalanus Worms in my Guppy tank. Well I had planned on changing over quite a few of the older babies (3 months old now) to the 30 long. To avoid over crowding. Well then I found the CWs so that had been haulted. However, I also discovered that the 30 gal also has the CWs. So both tanks have to be treated anyway. My biggest problem right now is that I can not seem to keep my nitrates under control in the 20 gal. I know this is because the fry are all getting much bigger and my BB can not keep up with them. I am also having ammonia arise here and there. But that will go away with water changes. But as soon as I miss a day it comes back. The water parms on my 30 long are perfect, the fish are all fine (for now) so since they also have the CWs, would it hurt for me to go ahead with my orginal plan and transfer some of the older fry? I am about to do the 2nd treatment on the 20 gal. And have been waiting until I decide on the 30 long. the biggest negative I can think of is treating these babies too many times for the CWs. Since the 30 gal is one treatment behind the 20 gal. (Hope Im making sense)... So what would you all do? Keep them in the 20 gal? Or go ahead and move some over? I would have some issues when treating for CWs for the 3 days. Because I would not be able to do any water changes etc. And it will be stressful enough to be in the medication for them. Let alone bad water. Once I get them all well and happy I was planning to give them away. It is just getting them there first. Any advice greatly appreciated!!!!
