Hi, i'm new in this forum. I have this fish since it was 15cm or so. Now growing to 60cm. These 3 days my pleco starts nibbling at his tail and when i put feeders(baby sharptooth catfish), they also nibble around his tail. But when i woke up all the feeders are gone, meaning he still eating. He used to be skittish when someone around, but he's been so weak that when i came closer he doesn't move an inch.
These are the pictures taken before:


And these are the pictures this morning:



And some of the scales are off, caused by all the nibblings i guess
