Goldfish Plant care? So, my family (aka my mom) got this goldfish plant as a house gift when we moved to our new place a few months back. I was put in charge of taking care of the plant, but when we were given it, it had a bunch of goldfish things that it grew, and now it is drooping slightly in the bottom layer, and from what I can tell it literally only has two goldfish flowers. How do I go about caring for this plant? Is it me doing something wrong? #NewPlantMom #help #GoldfishPlant #amidoingthisright #idontknowwhatiamdoing

This goldfish is in a glazed pot with no drainage. I did water it today, but the soil felt wet before I even watered it⦠maybe I shouldnāt have? I thought this guy like to dry out a little between waterings; I donāt want to get root rot. Is there some way to change Greg so it isnāt watered so often or by so much? (Correct glazed pot with no drainage was entered as type of pot when plant was photographed and added to plant list).
