Hey all! I noticed this morning that my tex was scratching his left gill (looking from behind). I have also noticed some scales missing on that side too. I took a close look at that side and noticed nothing unusual around the gill area. I have done different when keeping fish. I know I am pushing it only doing one water change a week, but I have no time to do it more, unless I can get away with doing multiple water changes in a row. I have also noticed an increased population of those little white worms things on the side of the tank. I know this means a healthy tank with higher than normal nitrates. Other than the few scales missing, the tex seems great. eating normally and such. I haven't introduced any new fish except for the pleco that I bought within a week after buying the tex. If I do multiple water changes, how long should I wait in between changes?? Also, can I fast my tex and pleco for 2 days?? I want to see if the tank will go back to normal. This is the first fish related problem I have had since I first owned fish (about 1 1/2 years now). I am not experianced in treating fish for parasites and other ailments. I do have an unused bottle of melafix. Since I am off this weekend, I planed on doing at least one water change Friday, Saturday and Sunday. Please let me know if I need to modify anything in my course of action. Thanks! You all have been really good to me!
