Here is the story. I recently transferred to the job I am at right now. On my desk is a poor betta in a bowl. I have been at this job for 2 months now. I asked about getting the betta as least a 5-gallon tank, but was told no. I was able to get him a bigger bowl, but that’s still not very good. So anyway, I’m leaving this job and transferring somewhere else. I begged and begged, I get to take the betta with me! Hooray, poor guy. He is supposedly about 3 years old, he looks pitiful though. The bowl he was in before was so small; he could hardly stretch his fins all the way. I am going to be setting up my 10 gallon tonight for him. I am going to take him home this week so he can get fed over the holiday. If I weren’t here, he would go with out food for 4 days because of the holiday. I don't know why they even have this poor guy.
Anyway, I know that when you start a new tank you should wait 3-6 weeks before adding any fish. I really don't want to keep him in this bowl any longer. How long should I wait to put him in the 10 gallon? Do I really need to wait the 3 weeks
