Comments (2)Definitely a Columnea. Goldfish plant is relatively common "common name" for them, as is "dancing dolphin plant." I'm not sure of the specific hybrid you have as there are many, but there's no doubt it's a Columnea. Mark...See MoreGoldfish plant

Comments (13)I can't tell if it is a Columnea or a Nematanthus from the picture. Both are sometimes called Goldfish plants. Nematanthus are also called Flying Dolphin Plants. Puglvr1's plant above is a Nematanthus. The plant in my profile pic is a Columnea (a NOID that I think is a C. gloriosa). It's really easy to tell them apart by the flowers, but you can usually tell by leaves too. I haven't grown Nematanthus if that's what it is, but I do have two Columneas. First, your plant looks very leggy to me. A lack of light would keep it from flowering. I grow mine in a northish corner window (a French door and a floor-to ceiling picture window) that gets a ton of indirect light all year long. I take them outside and hang them on my southeast-facing covered porch when temps are above 50F at night. I also think you're watering too much. In the summer, I keep them damp, but not wet. When they were in a 50/50 Pro-Mix/perlite media, I watered them about once a week or so in the summer. In the winter, I let it dry out completely before watering (about every other week or so), but you have to be careful about that because not all of them like to get that dry. I killed a C. "Aladdin's Lamp" by letting it get too dry. Keep in mind that these are epiphytes in the wild, so they grow on the side of trees. Lots of air around the roots. I use Better-Gro Orchid Plus Fertilizer on mine. I use a TINY bit with each watering (a little less than 1/4 tsp to a gallon) year round. If your gallon of water is blue, it's too much. Can you post a close-up of the leaves?...See MoreGoldfish Plant Help
Comments (6)Ty - they are not goldfish - they are Nematanthus - that's my boring diehard point of view! If you use "Nematanthus" when you do your google search - you will get significantly more useful information. Anyway - regarding your question. Yes - both these plants belong to the Gesneriad family - and the culture is similar. Nematanthus is hardier, can take more sun, but both do not like to have wet feet - standing water in a saucer - should be splashed out in half an hour after watering. Regarding brown spots on the flowers. I am thinking that it is probably a natural thing - the flowers are relatively long lasting, but if they were open for a month - that's probably their normal time to die and fall off. For Nematanthus to bloom - you need to give it a good light - midday sun is too much, but morning and afternoon sun is good - and the AV fertilizer - usually 1/2 of recommended amount is enough. Some of the varieties are seasonal bloomers - they do their thing for 2-3 months - and then stay green, But it is a lovely attractive durable plant even out of bloom. It is easy to propagate- if the stems become too long - just trim the tips and stick them back into the soil. If the soil stays humid -they will root....See Moretapla (mid-Michigan, USDA z5b-6a)
