Hey guys. I'm a new turtle owner. I have two (2) RES hatchlings with me and i named them Daniel and Stryker. Stryker is more of moss green in color and daniel is green apple in color. I have all the nessecities from the tank down to the UV bulbs and water conditioner.
Both of them were very active when i first bought them but after a week Daniel is just tucked in his shell, eyes closed and does not eat. Initially i just thought he's hibernating but since Stryker is still swimming around the tank, I'm fairly worried about Daniel's sudden change in behaviour.
What would be the best thing to do in this situation? Should I quarantine Daniel for possibly being sick and might pass it on to Stryker? And there's also the possibility wherein Stryker might further stress Daniel out. Should i observe him for a few more days?
