My Molly is being aggressive to my goldfish now.?

Question

My molly was removed from the tropical tank because of it's aggressiveness and put into the goldfish tank consisting of a 6 inch, 6 inch, 2 inch, 3 inch, and 4 inch goldfish. The molly was nipping and chasing one of the 6 inch goldfish and the 3 inch goldfish from what I saw so far. Will the goldfish get injured by the molly? The molly will only be in the tank until either a: it dies or b: I get him a new home.

Answer 1

I third that notion.......Mollies can not go in a Goldfish tank. Golds are cold water and Mollies are warm. Goldfish put out too much ammonia for most any other fish to survive in. I suggest running out and getting yourself a cheap 10 gallon tank set up with heater and filter, or else your LFS will probably take him off your hands for free.



On another note. I had a Dalmatian Mollie that kept attacking the other fish. I had never seen this behaviour before in a Mollie. I kept moving it from tank to tank until he picked his one and final fight with my GSP.



Please do not FLUSH your fish. This is inhumane and cruel, due to the fact that it will probably live in the chemicals for a long time, slowly dying. A better way to euthenize a fish is to place it in a cup of water and in the freezer. The fish will "go to sleep" The freezing water will slow down the metabolism in the fish, thus rendering it "dead" in other words.

Answer 2

Mollies are not known for their aggressive behavior unless they are taking advantage of a weakness in another fish. Of course there are always exceptions to every rule. I would like to ask a couple of questions about the platies though. Did you quarantine them before adding them to your tank? If not, it could be that there was something wrong with them to start with and they would have died either way. How large were they? 8 full grown platies might have been too much of a bio load all at once and might have caused an ammonia spike. The ammonia spike on top of the stress of transport from dealer to store and from store to your tank in a short time might be what killed the platies. Stress weakens fish more than anything else. The ammonia would cycle through fairly quickly in a well established tank but the spike would still occur. If the molly picks on other fish, then I'd move the molly to another tank. If it's just the goldfish, then I'd move the goldfish. Again, the usual cause for a molly to attack another fish would be a health issue with that fish. If this is not the case, then the molly should probably be isolated. If it is, then the ill/weak fish should be removed to a quarantine tank for healing.

Answer 3

Ha. I think the goldfish will only tolerate so much picking before it will fight back. Why would you put a tropical fish in a cold water tank? Even if it is nippy in the tropical tank, it is not a good idea to put it in with goldfish. 1. the molly is not cold water. 2. goldfish give off too much ammonia... Not a good move.

Answer 4

Get a tank divider and treat it like a betta. Put it back in the tropical tank with the divider because it needs to be in warmer temps than the goldfish. I personally don't like mollies because i've only had aggressive ones before. Good luck.

Answer 5

Are you really asking this it is stressed out goldfish are not tropical therefore the molly is stressed and atacking for his own knowledge of being safe. You might as well flush the molly instead of putting him in a goldfish tank

Answer 6

Mollies are tropical

Goldfish are coldwater



New tank

Answer 7

chances are, the mollie will kill off all other fish before it does. it will spread stress threwout the tank and thus creating disease.
