Tank Mates for Molly Fish?


Topic: I have bought 3 molly fish yesterday and need to get some friends for my mollies. I need a list of valuable roommates that work with my molly fish. Should I watch out for any features on fish like long fins or.. certain colors? I could really use some help here folks. My mollies are lonely and need some tank mates.

Posted by Megan G: Other Mollies, Guppies, Platys, Swordtails, Gourami fish, Female Bettas, Endlers, Danios, Minnows, Tetras, Snails, Shrimp. All ‘livebearers’ like molly fish themselves get along great. They are all the same aggression levels and breed in the same manner. These are Platies, Swordtails, Guppies, Mollies and a couple more. You can’t go wrong with more livebearers with your mollies.

All bottom feeders are going to do fine because they don’t bother the livebearers. They are only interested in what’s their next meal and where they are going to find it. As long as mollies keep to themselves.. bottom dwellers are going to be completely fine. Problems with bottoms feeders are very rare and your options are wide open.

Betta fish get along great with molly fish. Mainly female bettas but there are some of those “calm” males too. Females need to be in groups or else they get lonely. It seems female bettas cost around $4 U.S. dollars per fish so they are a touch more expensive than mollies.

Another great choice for a molly roommate is the Gourami. There are a lot of different species so you have a lot to choose from. Do a little research on the aggression levels of each species. Some grow up to 6 inches long so that may need to be taken account for too. These fish are one of my personal favorites. They have so much personality that they are my favorite fish to watch in my tanks. Just a cool personal note.

You will find that Angelfish do fine with livebearers but once they grow larger in size.. they do somewhat show a lot more aggression. I’m not really sure why.. because it’s not like they are tough or anything.


  • @Reply: Is your molly fish getting lonely all by it’s lonesome self? Why not give it a friend. Here are some questions regarding the compatibility of molly fish with other fish. Lots of great information to be absorbed. *Remember, all fish have distinct and unique personalities meaning that NOT ALL fish get along together. Even though there are “charts” to help us.. sometimes fish just clash. Watch your fish closely when entering.
