I noticed my Toadstool Leather has pieces of his head just fall off? I'm not sure what's wrong with him, does anyone know? It happened kinda suddenly, though he's been pretty happy....
Tanks been running since January
Water with Instant Ocean, Ph 8.4, stability
Light: Current #1501 only two months old
Last water change: last week, water tested this morning
Any and all input is most helpful and I thank you!!!!
