How is cheato supposed to grow? The two clumps I have, one in the sump and one in a hang on fuge, have their tops dry out and turn yellow and almost form a crust. There is also a bit of black/brown around the edges like it’s slowly decomposing. Below the water line it’s green and healthy. I’ve removed this top portion in the past and just happens all over again. Is this normal? Do you need to keep it submerged or can I just leave it?
