I am trying to classify a bacteria that I isolated from my red eared slider turtle tank. It's tested Gram negative, non-motile, oxidase negative, but catalase positive and ferments glucose. Under a microscope it looks cocci/bacilli shaped, but more on the round side . . any ideas?

The tests you did give pretty typical results for many bacteria. Most bacteria are catalase positive, many are glucose fermenters and most are oxidase positive. You have ruled out Pseudomonas however, which is oxidase positive. Some E. coli are nonmotile, some are motile. Proteus is motile so that is ruled out also. You will have to do some other tests to be sure.
