Ok so I have a blue dot red mushroom and I throw formula two pellets in the tank for the helmets and stuff and some of the pellets fell on top of the mushroom. Then the mushroom started to close up to put the pellets at its mouth I guess. Clearly he was just eating. I come back in like three hours later and he regurgitated all the pellets. They were in a mucus casing just sitting in a group together on top of his mouth just sitting on top of the mushroom. Is that normal? Like what happen?
