I need a possible answer about my mollies. I have a 10 gallon tank and (I know it's over crowded but they're mostly fry that's survived) I have 2 Pleco's (different species but now sure what), 3 Neon Tetras, 6 Guppies (2 females, 2 Fancy Finned males, a snakeskin guppie and a baby female) and 3 Mollies (a male Creamsicle, a female Lyretail Dalmation and a baby Dalmation). I've had all of my fish since I started my tank 3 years ago the only new one's are the Mollies. The Creamsicle is constantly picking at the back end of the female dalmation. She'll start to pick back so I put her in a breeding net (she is pregnant) because I was afraid they'd kill eachother. Today I put her back with the rest and both creamsicle and dalmation were fighting my beating each other with their tales and they bother had their dorsal fins completely straight up. Any clue why they're doing this and how I can fix it?
