Trying to pinpoint this disease which is effecting my pleco's and catfish. I don't know if this is a bacteria or fungus, or where it came from. I have a 125 gallon, gravel bottom about 1/4" above the black plastic frame, ph is 7,4, wet n dry for a 200 gal tank, ammonia, trites are zero, trates never go above 10, 15 ppm. The water gets changed two times a week. Fish load is 9 discus, was 3 pleco's, was 6 catfish., and was 10 gold head rams. The rams were breathing fast when I got them... I noticed they were breathing fast in the LFS. Probably never should have bought them. One by one all the fish passed. The rams died 1 or 2 every day or so with no signs of disease. I don't know how long the pleco's or catfish had whatever disease it was as they started hiding, plus you rarely get to see the bottom of the fish. I lost 1 discus probably due to stress from the meds (no outward signs of disease). The LFS said it was a bacteria. I tryed Metroplex for 2 weeks. After that I used Kanaplex for 2 weeks. During this time I was changing the water every other day. Directions for Metro and Kana say to dose every other day. I changed the water just before the dosage was due, and right after the water change I dosed the tank. I did the water changes to keep the discus happy. In retrospect perhaps that was a mistake. After going crazy for a few weeks, and multiple opinions, I took everything out of the tank. Driftwood, fake plants, gravel. I took 1/8th of the gravel out every week, so as to not disturb the good bacteria. I am down to the last foot or so of gravel. I still have 8 happy discus in an almost bare tank. To give the discus a break, about a week ago, I stopped the meds and turned on the UV lamp in the 125.
I thought whatever it was might be gone.... BUT, the pleco in my 75 gallon tank got it. He has a white spot on his bottom which I think is the start of whatever disease I am dealing with. The spot was about the size of one of your smiley faces (maybe slightly bigger). There is only 1 discus and 3 pleco's, and 4 clown loaches in the 75. The clown loaches seemed to be unaffected, but as a precaution I moved them to a 20 gallon quarantine tank I just set up. I also medicated the 75 with Metro and Kana... but that did not seem to help. Last week I started with API Melafix (for bacteria) and Pimafix (fungus). These 2 are "natural" items, not really meds. The pleco's seems to be responding... the white spot is getting smaller... I started those 2 meds last Thursday (28th).
I don't understand how the disease jumped from one tank to the other. I was very careful to wash everything that was in each with bleach after every use. When it became clear, I had an issue I purchased new nets, water change equipment, test kits, food, etc. I used rags once and washed. I was careful to wash my hands anytime I went from one tank to the other (such as feeding times). The only fish which was common to both tanks is a 4" Albino Discus from Asia. He is a nasty little thing, and I moved him from the 125 to the 75 so he couldn't run the others to death.
Note... My memory is vague, but at some point I might have taken some gravel from the 125 and placed it in the 75 to jump start the bacteria. I don't remember if I actually did, or when, but it is a definite possibility.
Sorry for being so longed winded... I just want to knock whatever is in my tank(s) out !!! I posted on another forum but was not pleased with the 1 reply which I received. I would really like to put this to rest, as I would like to have a fully decorated tank and add a few more fish. I hope the pictures work...
Here are 4 pictures....
