Hello fellow fish people, My name is Netty, and I am writing you today (Jan, 9th, 2012) to see if anyone has any opinions on how to help me with my sick fish. About 2 weeks ago, I cleaned my fish's tank. I am very particular about my fish. Most of them I have won at carnivals, but the ones that are sick were ones I bought from a pet store. They are all over 2 years old. I have a big black Moor and a medium sized calico moor, along with two black mollies. They have always been healthy, and I did not do ANYTHING DIFFERENT, or out of the ordinary when I cleaned their tank. The day after I cleaned their tank, I added a small pleco, then the day after that the pleco was dead. Then the following day my moors were sinking to the bottom of the tank and were hiding under/in their tunnel. Finally, on the third day of them acting like this, I noticed that my large black moor had ick. I assumed that it was introduced by the pleco however, I have another tank and I also bought a pleco for that tank and put it in that tank on the same day as the other (now dead) pleco was introduced to the other tank.... and he/she and the rest of the fish in the other tank are doing fine. What I have come to as a conclusion for the sickness of my moors and mollies is that I must have stressed them out while performing their tank cleaning. Anyway, once I gave them the ick meds, they seemed to come back to life, and have lost their ick spots. However, the large black moor still has some (I'm guessing) scars left from the ick. It looks as though he has white scars on the end of his tail that look like ick, but more like weakened parts of his tail that now have holes or perforations in it. After I got rid of the ick, the black moor then developed some fungus on his head, and the other calico moor now has some red marks on/under it's skin that look like (not raised) blood blisters. I have done EVERYTHING I CAN THINK OF to help these fish. I have sterilized their tank and all the stuff in it... I even bought new gravel. I have added ick meds, fungus meds, parasite meds, all in one meds, melafix, check the ammonia and nitrate level and have treated accordingly. I've also treated with quick cure, start right slime coat additives, I've used clear water , water conditioning, and have used Nutrafin Cycle Biological Aquarium supplement.... and I have been doing (every 3 to 4 day 25% water changes - using treated water that I let sit with the cap off for 3 plus days. I have also raised the salt content of the water (using aquarium salt) from 1 rounded tbl.spn per 5 gallons - up to - 2 rounded tbl.spn per 5 gallons..... PLUS, I have also raised the temp in the tank to the top of the “certified okay green zone” on the thermometer stick from where it had been (which was right in the middle of the “normal -or- okay” green zone section ...... I have cut back on their food, and have added some cooked peas to help with constipation. I have even gone as far as physically picking my black moor up, and gently wiping the fungus with Povidone-lodine wipes. And almost immediately after doing this, the fungus seemed to go away, but left a “red” mark in it’s place..... The red mark was either from the color of the iodine or from the underlying wound (or raw spot) that had previously laid under the fungus. It didn’t seem to go away once re-entering the water..... so that lead me to believe the red mark was not the color of the iodine, but a red raw spot on the moors head that was there before I started the gentle wiping and was just uncovered by the removal of the fungus. Now......After all that......and after adding the second dose of the fungus treatment........ My black moor has seemed to develop MORE FUNGUS, AND IT IS SPREADING FROM HIS HEAD, DOWN THE TOP OF HIS BODY????????????????????? Obviously my fish are VERY STRONG, AND HAVE A WILL TO LIVE THAT FAR EXCEEDS MOST HUMANS..... but I am very worried that I may lose them. I know that they are only fish, but I have raised them from “minnow size” to now being over 3 inches (for the mollies) and 5 inches (for the moors) and they have now become pets that I care about as much as I would a dog. I am at the end of my rope........ I am not even sure that I have listed all that I have done to be perfectly honest. PLEASE........IF YOU HAVE ANY ADVICE, PLEASE TELL ME A.S.A.P. Thank-you for your time. -Netty- P.S. ---- I also removed the carbon from the filter while I was using these treatments, but I had to add it back yesterday just due to the water quality and my own personal paranoia of there being chlorine and/or hard metals......... I also went out and bought both tanks new (and much better) heaters and thermometers just out of fear that the temp could have been the culprit ........ I am totally at a lose, and at the end of my rope..... PLEASE HELP ME IF YOU CAN!!!!!!!! IT IS NOW 12:09 PM ON THURSDAY JAN. 9th, 2012...... If possible, please email me back TODAY with some helpful answers.... I don’t know how much longer my fish can last?!
