I recently was given two oscar fish in a 29 gallon tank. I know, I know the tank is too small. The oscars are still little and are getting along well for right now. I am in the process of getting a larger tank but it may take while. How long with these little guys be ok for? I would like any information I could get on raising these guys. Feeding, water changes ect. I don't have the option of giving them back and I have kinda grown attached anyways. Please Help I don't want them to get sick and die because of my inexperience.

Thank you in advance for the help
