So I currently have only one fish in a 25-30 gallon tank of brackish water. He's a silver Molly with black spots named Rorik, and ever since his mom died, he's been alone. As a social fish, I worry about him, so I've been thinking about getting him a few tank mates. I'm trying to be careful, one new fish at a time, and I was thinking about getting a female Betta as his first tank mate in several months. Now I've heard that female Betta are fine with nonagressive Mollies. The temperature of the tank seems just right, the water is in nice condition, but what worries me is Rorik himself. He's been alone for so long, he may be a little too used to being that way. I dont plan on getting any other Mollies, because I really don't want a mic up that would result in a plethora of fry. But can anyone suggest other fish to put in with him? Can I put in a female Betta now, or should I wait until after there are a few other fish? Can I start with a baby female Betta, will it help with her temperament if she's exposed to other fish at a young age? There is room to hide, a large log with multiple exits. I have so many questions, thank you to all who answer!
