My turtle's shell is green. Is this normal or should I be concerned?

Pet's info: Reptile | Aquatic Turtle | Female | unspayed

Hi. This is Pikachu, my friends turtle. He went to a vacation and gave Pika to me to look after. It's my first experience with turtles and I'm little concerned about Pika's shell's color. I researched a little and got worried. I live in Azerbaijan and I'm not familiar with vets here. Plus because of the quarantine i can't go and search one. He told me to feed her with gammarus once a day. I hope somebody will help me. Thank u

Hello! What a cute turtle! You are a lucky pet sitter! I'm not certain if you were referring to the top shell (the yellow color or the green color) or the bottom shell... So I will ease your fears and just say that Pikachu looks very normal. The green stuff on the top shell appears to be algae. Not a big deal unless the tank water is completely green. Then it might need to be changed. Everything else looks great! Thanks for contacting us and enjoy!
