Fluffy vs. Food round2

So it's been several days now, Fluffy looks like he's enjoying the new and improved water filter. Food is still alive and well! He looks a little freaked out, he spends most of his time hiding up in the leaves of the onion plant. Two days ago i came home to fluffy having a bloodied side and he lost a scale. I was really worried but it healed up back to new in two days flat.
