So I did a major no no and set up a 5.5G with a male and female multi. They have now matured and are breeding like champs so obviously the 5.5 isn't going to cut it much longer. Some of the fry are already about 1/3 full grown. So my question is how do I move the little dudes? I'd like to move everyone as a group so there's no issues in a larger tank but don't want to hurt the fry and some of them are still pretty small. If I just move the adults and wait for the fry to mature is this going to cause aggression issues when I finally introduce them to the larger tank?
Thanks for any advice as I'm kicking myself as I did know better and still put them in a too small tank to grow as a family.
