Single Sickly Bumblebee Platy

[Wonder Boy]

We've got a single Bumblebee Platy with a sunken belly and is generally looking sickly. I need help figuring out the problem, pictures below. Here's the tank details:

• Tank Size:    56 gallons
• pH:                7 
• Nitrates:       ~40
• Hardness:    150+ ppm
• Nitrite:          0 
• Ammonia:     0 
• KH/Buffer:    ~40 ppm (need to add more crushed coral)
• Water Temperature: 75 degrees

The little fellow seems to be eating and the rest of tank is fat and happy. We're feeding a combo of Xtreme Krill flakes and Nano bites, Hikari frozen Brine, and Tubiflex worms. It's a well stocked tank with Salt and Pepper, Green Lantern, and Blue Wag Platys, as well as Serpae Tetras, and a few mutt guppies. The thin fish did get nipped a while ago, before we got the Tetra aggression under control. There's many plants in there including swords, water sprite, and Japan. 

What do people think? Worms? I am moving him to our Quarantank so he can get some solo attention.

If he's eating ok and still losing weight it could be internal parasites I would treat with paracleanse it can take 2-3 courses of treatment

Also, from her tailfin, it looks like she got nipped pretty recently. Potential parasites plus stress from bullying can really cause issues.

The solo attention (both w/meds and then grub) sounds like a solid plan to monitor and fatten her up.

Two doses of Paracleanse and some solo feeding seems to have helped. Any concern for the white near the head?

There a few things it could be an injury or over production of the slime coat or a bacterial infection I would treat with aquarium salt 1 table spoon for 2 gallons and monitor for now if it starts to get worse I would treat with kanaplex
