I’m concerned that this shrimp has some sort of parasite or infection. I consider that it might be a leftover molt but even still I’m wondering what I should I do.

Tank Information:

20L, 40L Sponge Filter, Dechlorinated Tap Water (Saskatchewan, Canada), Ammonia = 0 Nitrite = 0, Nitrate = 15, and pH = 7.5. *I do not yet have a GH or KH test but the calcium source is cuttlebone, tank photo is included at the end of the pictures.

Pests, Meiofauna, and Algae:

Hydra, visible hair algae on plants and walls, many limpets, copepods, and daphnia present.

Stock:

Neocaridina Davidi, Thiara Scabra Snails, Anubias, Java Fern, Monte Carlo, Christmas Moss, Lucky Bamboo, Marino, Salvinia Minima, and Suswassertang

Substrate, Organics and Hardscape:

Gravel, Lava Rock, Pagoda Stone, Driftwood, Almond Leaves, and Cuttlebone

20L, cycled for a month and a half with 0 ammonia, 0 nitrite and 10 nitrate. Planning to stock with a couple thiara scabra and 10 Neocaridina. I’m wanting to continue with the densely planted jungle vibe. The substrate is gravel mixed with lava rocks and clay pebbles (I believe they’re just pumice with red clay powder baked onto the outside). As stated in the title I’d love to hear anyone’s thoughts!
