If you recently added Cherry Shrimps to your tank, then they will lose their color until they get more comfortable living in the surround environment. To speed up this acclimation process, we recommend turning off the aquarium light for a day and providing them with plenty of hiding spots.

Hi so it's been about 1.5 months after getting some cherry shrimps and i noticed, my males are turning transparent but my females are staying reddish-orange i think.

What color does shrimp turn when its bad? The first is discoloration. Raw, fresh shrimp should be gray or white in color and may even appear translucent. If you notice any spots on your shrimp, it's a good idea to toss it. In contrast, cooked shrimp should have a bright pink color — not faded or gray.

My cherry shrimp was acting strange last night -- furiously doing laps around the tank then sinking to the bottom. Today he's acting ok but he's turned almost clear.

First three and gH are most important. They shouldn't be losing coloration, they should only gain coloration to blend in. A loss of color is a sign of stress. Algae wafers won't be enough for them, you'll need a solid shrimp pellet. That may be your culprit, just watch your nitrates too, unfortunately shrimp are notoriously sensitive.
