Last night I boiled a small amount of romaine lettuce, red cabbage, and carrot. I left this in my 20 gallon tank overnight and removed it the next day. In the morning, my pleco‘s stomach was blue and a tiny bit big, but it seemed normal. I had a piece of lettuce in the tank attached to an algae magnet, which the pleco was near. I had to move the magnet to remove the lettuce, which may have stressed the pleco out. The pleco hid under the driftwood for most of the day, which is normal. However, later, it went to the new sponge filter for the first time, which may have freaked it out. I turned off the light to hopefully let it calm down, but it began spiraling. It is currently hiding in my Java Moss, which is something it never does. My water levels are fine, and all of the other fish are acting fine. Is something wrong, or did it just get freaked out?
