Several vendors have been posting really nice wild rainbow chalice colonies lately. I've been tempted to buy one but I recall hearing from someone that wild rainbow colonies are tough to keep. Does anyone know if there any truth to this?
I don't believe they're any harder than aqua-cultured. Depending on your lighting, they can show different colors than what might be pictured. Ask the vendor their lighting to make sure you'll be able to replicate the colors in your tank.
