Hi! My name is Drew and I have a res (Sergio) that is about 3 inches big. I got him as a gift about 3 months ago. He lives in a 20 gallon aquarium equipped with a heater, water filled to about 6 inches, thermometer (which is usually between 75-80 degrees), a large basking area with uvb lighting and "hiding spot", and a filter. He usually eats floating pellets,freeze dried shrimp, or freeze dried krill. About 2 weeks ago,Sergio stopped eating. He's usually quite the greedy fellow, but now he just swims away when I try to feed him. A week ago, I tried to change it up a bit and give him live fish. Out of the 3 I put in there, he nibbled at one. I'm quite worried about him and will take him to the vet as soon as I can, but money is very tight at the moment and I am unable to.

Besides eating, he is acting exactly the same. Swims around, basks for a few hours, and even walks around in my backyard with me. If anyone has any suggestions, I would really appreciate it. Thank You.
