I got 3 dalmatian mollies tonight (2 male 1 female) and after adding them to the tank one of the males was really aggressive. He has been chasing mainly my tiger barbs around. I was afraid it would be the other way around if anything. The fish are about the same size so it isn't like the molly is bigger than the barbs. The other male and female are fine and non aggressive. I just wondered if this is normal? Should I be worried about it? The barbs are faster so it can't catch them but I don't want them stressed out. I am hoping tomorrow it has calmed down some. Anyways, any info would be great. Thanks!

I have had this happen to my fish several of times. Mollies and Swordtails. What he is doing is showing his dominance in the tank. Is it doesn't stop soon or it gets more violent, get a breeder basket, and put him in it. The basket is large enough to house him, and the mesh sides won't hurt him. Keep him in the basket for a few days, and then let him out. Watch him and if he fights, put him back in. This worked well for me, if not, you need to find a way to seperate the males, or get more females.

It calmed down a lot today. I will keep an eye on it and if it keeps happening I will do that.

Just for the record, what color of molly is he? Almost every black sailfin molly Ive had has been overly aggresive, wheras, Silvers tend to be curious, and gold creamsicle tend to just mind their own buisiness.

i have a problem with balloon mollies attacking each other. i had 2 females 2 males and other random fish, but the 2 male mollies were fine for months and now i had them separated in a breeder net for a month. I felt bad so i switched one male out and put the other in for a month. Today i decided enough is enough and i took the male out of the breeder... (i want my tank breeder net-less).. lol so anyway 1 female is dead due to ick and whatever else ,i got to it too late so now its a bunch of babies other fish and 2 male mollies n 1 female mollie.
but the 2 male mollies are attacking no chase just straight up old school fighting each other. i dont want them to kill eachother, i like my orange balloon mollie better then the black one lol but i want them to live in piece and now the babies are ganging up on one of the mollies during the fight please help!!!!




PS
55gallon tank
all readings are normal
all fish are healthy (any outbreaks are contained to one fish only (black female mollie always gets body fungus not sure why and always treated the fungus with positive results))

the balloon mollie that is aggressive is all black and the other one is orange
