My red eagle discus has been recently been very lethargic. It stays upright in the middle of the water column but rarely swims and never eats. I have been treating with a mild dose of metro for a few days but haven't seen any improvement. I took him out today for a salt bath and did a scrape on his slime coat to look for parasites. I found about 6 of these very small worms that move like an inch worm would but they are very microscopic. I also noticed a lot of these large round objects in his slime that do not move and am not sure if these are parasites or just something in his slime coat. The parasites are almost clear in color and appear to be perfectly round from head to tail ( no hooks seen )
