In my 20 gallon tank I’ve notice for the past couple weeks any new growth on almost all of my Anubias plants are growing in with holes on them. I have a few Anubias nana and a coffefolia. The coffefolia has always put out a new leaf every 2-3 weeks and was growing super healthy. It was the first one I noticed with the new leaves having holes. They look as to start to grow normal then when they open up they have holes in them. I will get some pictures up tomorrow of the plants.
