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: I’ve been keeping these fish for around 10 years now and they are some of my favorite. They breed super easy and that enables me to sell them on the side. They are also super hardy and easy to care for! I just love these fish. Lets answer your question now.

Best Tank Mates for Molly Fish

The best tank mates for molly fish include other Guppies, Platys, Swordtails, Gourami fish, Female Bettas, Endlers, Danios, Minnows, Tetras, Snails, Shrimp, and other molly fish. All livebearers like molly fish get along great together. 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.

  • Guppies
  • Swordtails
  • Gourami Fish
  • Female Bettas
  • Endlers
  • Danio Fish
  • Tetras
  • Snails

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.

Molly tank mates for my 55 gal?

I have 3 female mollies 1 platy (plan to get 2 or 3 more) & 3 corys. What is compatible with these? Not trying to overcrowd my tank but it seems so bare.

Hey guys! Thanks for the add. I came seeking info on basic Molly care. I know a fair amount about bettas, but that’s basically all I’ve had (besides their tank mates). I recently acquired a single male Molly, and haven’t been too sure how to give him the best care. I did get a female to go with him. I will need one more to have a happy group, correct? Also, what type of filter, etc is best for them?
I’m new to Mollies and one of my fish had babies. I didn’t even know she was prego. By the time I noticed babies (could have been overnight) in the tank, it looks like most got eaten by the other fish. We caught the remaining 7 that were good at hiding in the plants and put in a breeder box. I also bought fry food. Anything else I need to Do? Do they look Ok? Seemed more active yesterday.
I’m breaking my rule about posting in a group before observing it, but I need help! I’m very new to mollies, and when I got them, I stupidly didn’t know they would have babies. Well, 2 weeks later, one just had them. I put up a tank divider beforehand, and I don’t know when she had babies…either overnight or popped some out slowly over the night and morning. I saw them in the rocks, and panicked because they could get to the other side with the other fish. I moved mom over to another tank and caught the babies (only found 5). So now mom and babies are in a separate tank. Question is, is she done having babies? How do you even tell? I haven’t seen her have another (actually never saw her give birth to any of them). I feel really dumb for not just leaving them alone in the main tank also 😒
Give it a maximum of 48 hours for all babies to come out if she is not stressed. But you’ll have fry since she can keep having up to 6 without any make as she can store sperm for that long.
How big is the aquarium she is in now? If you have lots of plants and decorations they will hide and be ok. Is this other tank shes in cycled? Heated& filtered? I keep my guppies with the adults and they can get away and hide in the plants i have all over including floatinga few.
The small tank I moved her to is a 2.5 gallon with a heater and filter. I used water from the main tank to fill it and some of the rocks as well to hopefully make it a little less stressful. I have a fake plant..thing in there that’s perfect for the babies to hide in.
Hei hei , do any of you know what this lobster is really called ?  And could anyone say is it wise to let this one live with our community tank with our mollies and other fish ? How big is the risk of it eating or harming one of our fish when the lights are off and the fish are sleeping ? here is a picture of my fishies

I’m an Aussie and we have had them we call them ‘yabbies’ or they are known as blue claw, there is a red version called a red claw, they will nip at the Molly’s and all other fish you have. Otherwise they are pretty cool.
In the PH we call the blue crayfish or blue freshwater lobster I’ve had one and i would not recommend slow fish with this because they tend to eat fish as what she said and mine even got to some tigerbarbs that are slower or weaker in the pack so if i we’re to recommend fish for a community with the blue crayfish i would recommend a fast species that likes to stay at the top.
I have had similar Florida native species and they will capture and eat live fish. They are scavengers but can be aggressive if hungry. I found they will kill and eat sleeping soft tissue fish. I let mine go after a few weeks of missing fish. Solved the issue too.
Do you know much about them? I just wanted to let you know they molt and will look like they died if you dont know about it. Just leave the shell in for him to eat. When they are small and well fed they will do it every 2 weeks or so.
hmm, yes, i dont know much about them, thats why i asked for its name also, but somewhere we read that it will change its shells, we just didnt know how often it may happen 🙂 

Do you have any suggestions of how warm its water should be ? the fish shop lady said that we should feed it 3 times a day  so 3 algae tablets a day 

Dont feed it that much lol Once a day and do a variety. Algae tablets, shrimp tablets, excess fish food if he lives with fish. Also be sure to give some fresh veggies like kale, romaine lettuce, cucumber, zucchini ect. Dont over do protein. I did with one and it effected it shell and one molt just didnt go welll and he didnt survive much longer. I would just have the water at room temp. You can use a heater to regulate the temp but dont have it set for above 20.
My suggestion on temperature could be just about room temp. is fine because crayfish are pretty hardy but if it your area gets cold then add a heater although I’m not really sure about the temp. when adding a heater.
