Adult YBS refusing to eat and slamming glass.
To start things off, I am new here so I apologize in advance for anything.
I have had my Yellow Bellied Slider(Rupert) for 3 years now. He is currently in a 180 gallon fish tank with some fish that he has lived with for a while. He does not eat the fish, but he loves eating his plants, and raw shrimp. he NEVER passes up shrimp.
About a month ago, i rescued my cousin's baby YBS. They have seemed to get along just fine, the little one even climbs on top of the big one to bask every day.
Well, about 2 weeks ago I started waking up to the big turtle slamming against the glass swimming against it. He has done this every morning since then, and REFUSES to even look at food. Shrimp, pellets, bloodworms.....I tried buying fresh kale and fresh lettuce. The little one is eating everything that Rupert ignores.
He is more active than usual, swimming against the glass, and he is still basking alot. I tried letting him run it off outside, but it didn't seem to help.
I am so frustrated I can't even sleep past 8:30 AM because of him slamming the glass. I would really appreciate any advice I am really upset. Do you think he is mad about the other turtle???
