Hello everyone! so the weirdest thing happen to me - it all began after I bought 2 new dojo loaches for my 20 gallon tank. approximately a week later, Goldie (dojo) passed away on me. Soon after, I noticed my dwarf gourami, Monsier Pimp, had a huge ulcer on the side of his body. I called up a local expert and was told Melafix should patch it right up. It looked like it was getting better, but suddenly, it got 10 times worst, and it was digging through his body hardcore. Right after it got worst, Milly (dojo - not a new one, tho) had a torn back fin, and was having equilibrium problems (out of nowhere too... had checked on all of them earlier and she was fine). She died approximately 15 minutes after I found her. Monsier Pimp (dwarg gourami) was soon bloating up and not showing his normal activity... he was hanging at the corner of the tank constantly, and taking gulps of air every once in a while. I treated the tank with General Cure, Tetracycline, and Melafix. It took him a good two weeks to finally let go (worst experience, btw, watching him die slowly). Now my tank is still undergoing some treatment with Pepso food in addition.
I just visiting the Petsmart that I went to buy the dojo loaches, and noticed ALL of their tank system had fish exhibiting this, especially the dwarf gourami tank (durr), and the fishkeeper there didnt notice it till I brought it up.
What do I do? The tank is not the same after so many of its companions left, and I would love to have it up and running as it was before, however I need advice as to how to make sure its all going to be ok for that to happen again. Quarantine in a hospital tank while cleaning out the home tank? suggestions please!!!
