I recently got an Albino Oscar for my 10 gallon tank before I new that 10 gallons was to small. He is in there with a Bumblebee Cichlid and a small algae eater. I understand I need to get a bigger tank. My question is how long will he be healthy in my 10 gallon if I do frequent water changes. He is one inch in size. I am going to start saving up to buy at least a 55 gallon in the next month or two. Then eventually upgrade to a 100 gallon wants I move from my apartment to a house. Is this time frame okay?
