Okay so I have a question...I want to get some cory's for my tank, but I'm not sure how well it will go over with my betta. In the past I've had an ADF, but it died after a few days. I am not 100% sure, but I think my fishy might have had something to do with it...I also had a ghost shrimp which my betta looked at as a snack, even though that was not it's purpose. The only other surviving aquatic life in his tank besides plants, is my snail. I went to Petsmart today to see the cory's and they seem really energetic. I've read they need to be in a group of six or more. Right now I have a 10 gallon, so I think it's big enough for a couple. My question is if I should get them or not. I don't want to have them die, but at the same time if there are six in there maybe they will have a fighting chance. Any experiences, suggestion? Please only answer if you actually know about this. Thanks.
