It looks like normal acclimation melting. Some plants shed their leaves and grow new ones when they need to acclimate to new water parameters. How long have these been in the tank? Can you tell me more about the set up in question? How many hours of lighting, how is the flow in the tank, do you inject co2?
Do you have water test parameters? It would be easier to figure out what is wrong by running down the list of conditions.
They are fairly new only about a month old. I didn't know they melted my crypts never melted.they were added at the same time. But I run light 10 hours I inject co2. Maybe the flow could be upgraded. Thanks for your help. Glad to know it doesn't seem like some type of dissease or deficiency.
