New Pleco owner of a zebra and he’s not doing well already. I’ve had him less than a week and can’t figure out how to help him. He’s not eating and color is fading in and out and some white spots come and go. Tank mates: a white betta, 4 albino Danios, 3 shrimp, 4 snails. Plants: dwarf hairgrass, Madagascar lace, tiger lotus, lucky bamboo, alt. Renikii bonsai tree. Co2 injection, Fluval 307 canister filter on a 55gal tank. Just did a water change when I got him. Dosing water with Iron daily and flourish 3times a week.

Firstly, welcome to PlanetCatfish!
Sorry to hear you're having problems. Can you confirm we are talking about the same fish? ?
What's your water temperature? Have you tested the water for levels of Nitrite/Ammonia/Nitrate?
Have you been back to the store to see how their fish are doing? You may find there's an issue with the batch, so if it's close by, worth a visit.
