Hey guys! So I currently have a 20g tank with 1 Female Balloon Molly, 1 Female Marbled Molly, a Betta, 3 Ghost Shrimp and 2 African Dwarf Frogs. My tank is pretty well planted with plenty of hiding spots but I've still noticed that my female balloon molly will still go way out of her way to try to attack my Dalmatian molly. She constantly chases her all day back and forth throughout the tank and even lunges at her at full speed. Luckily my Dalmatian molly is much faster then her. I've tried separating them before by putting my balloon in a 10g to "calm down" for a few days. Odd thing is, whenever I add her back to the tank they both act like best friends?? It's the weirdest thing I've ever seen with mollys. Like for a few days after adding her back into the tank they'll swim with each other, sleep in the same decoration and even rub on each other kind of like they're cuddling. But then sure enough my balloon molly will start acting aggressive again. I've thought about getting rid of her but I got both of them together and I've had them for about 8 months now and I'd be really sad if I had to get rid of her at this point. Weird enough they're like kids to me haha. Any advice guys? I'll also include some pics so you can see them!!
