It’s most likely that a string of dolphins will fade if too much water is thrown at them. To revive, you should use only water when the soil is parched since the roots need time to dry after being overwatered. People sometimes check only the soil, but you should also check the drainage holes and remove any extra sand blocking the water flow. Test this by drenching the plant with plenty of water and checking whether the water is drained. Everything is fine if the water is drained; otherwise, fix this problem right away.
