Hey!
I have a baby res for about 3-4 months now (dont know his exact age). Today i noticed that the part of his shell right above his tail is soft. Rest of his shell is fine.
I feed him primarily saki hikari turtle pellets and have fed him chicken liver only twice.
His name is groot, and has a exo tera solar glo uva + uvb ballasted basking light, though he prefers to stay in the water mostly and very rarely every basks. He is very active whenever he sees someone and immediately starts begging. His appetite is also normal and have seen no change.
Is this normal? Or is this the sign of some kind of deficiency?
