I was so happy when Oliver moved back into his home tank a few weeks ago. Tried to get a closeup of the clean scales on his side, but this was the best I could do- in the baggie ready to float. Water spots and smudges on the plastic obscure it, but yes his scales were clean of parasite.
LEDs, give it more light.
Then I finally saw the missing buce, when looking for a snail. It was snagged among some small rotala cuttings I had replanted behind the new log. I wedged it into a crevice here on the end of the log. (And now I think the smell was maybe a dropped trumpet snail).
Last night I did a partial water change. Today went and got API Fungus Cure- which has malachite green. Some people say it kills their plants (no warning of this on the package) and I know it can stain ornaments and sealant. I set up a quick ten-gallon hospital tank again- plastic plants, threw in some sacrificial duckweed floaters. When I first put in the dose of meds Oliver seemed to feel better- he was swimming around actively. Now he lies on the bottom for long periods of time. I am keeping a close eye on him... Treatment is only four days, and then one more of water changes to clear the water (and make sure he is symptom free before I put him back in the home tank). I am not sure how he got the fungus. Maybe it happened when I fed him a moth larvae and didn't realize he had spit it out after I left the room. I found it the next morning in his tank- I bet it fouled the water. Although I tested it and there was only a slight bit of ammonia 0.05, no nitrites, nitrates 5ppm.
