Setting the Perfect Aquarium for Balloon Molly Fish

To keep your Balloon Molly Fish healthy and happy, they need to be provided with an optimal habitat. Some key considerations are as follows:

Tank Size and Setup

A minimum of 75 litres of water can be ideal for Balloon Molly Fish because though they are not large, they are very active swimmers that need water space to thrive. The tank must have a good filter mechanism to keep the water clean and reduce the frequent change of water.

Water Conditions

Balloon Molly Fish are very tolerant, but ideal water conditions for them are slightly alkaline, between pH 7.5 and 8.5. Their temperature requirement ranges from 24°C to 28°C. Constant testing and maintenance of the water will keep this steady and your fish happy.


Tank Mates

These fish are peaceful and social, thus making good companions for other non-aggressive species. They will quite get along with other mollies, guppies, and swordtails. However, they should not be combined with fin-nipping or aggressive fish, because that would make them stressful and often present health problems.

Feeding Your Balloon Molly Fish

Your Balloon Molly Fish needs a good diet for it to stay healthy. Balloon Molly Fish are omnivores and will eat almost everything. Feed them with the finest fish flakes or pellets available for livebearers. Supplement their diet occasionally with live or frozen foods such as brine shrimp or bloodworms to provide some variety and nutrients.

Be sure not to overfeed. Offer a small feeding 2-3 times a day and remove any uneaten food after a few minutes to avoid contaminating the water.

Preparing the Perfect Breeding Environment

Provide breeding conditions: your tank should be well-maintained and the water conditions ideal. It should include many hiding places, like plants or breeding boxes, for the fry (baby fish) to hide in once they are born.

Gestation and Fry Care

Female Balloon Mollies have a gestation period of about 4-6 weeks. Since they produce live fry, you'd know ahead of time when to expect the little ones to arrive. Once they have birthed, it's extremely important to separate the fry from adult fish so they don't become lunch.

Feed them finely crushed foods or specifically formulated fry foods so that they grow healthy and strong.
