I’m completely baffled...
A few days ago I noticed a few pale, almost yellow leaves among my Cryptocoryne parva. First there were a couple, and then half a dozen different plants with similar leaves. Since no serious change in water quality, fertilizers or lighting have taken place, I was confident that the plants should not be distressed in any way. So I decided to closely watch them for a few days.
Upon closer examination, I realized these are completely different plants. Clearly, hitchhikers. The veins on the leaves are prolongated and stretch from bottom to tip. They also have pinkish spots. In a way, they resemble Blyxa japonica, but very tiny ones. See close ups below.
But where did they come from? What kind of plants are they? I did have Blyxa japonica, but I removed all of it at least six months ago. And B. japonica never sent such tiny offshoots.
Has anyone seen something similar to these? Please help ID.
