Why do Mollies get their fins up
Male mollies often raise their dorsal fin when threatening rival males or trying to impress potential mates..
How do you know if mollies are mating
Usually, a female goes vertical when she agrees to mate but I have noticed that the male mollies continue to chase the ones who are swimming away from them. Even if a female swims slowly it’s also the sign that she is agreeing to mate and allowing the male to chase her easily.
Why is my molly fish swimming vertically head up
Molly fish tend to swim vertically when they are stressed. That usually happens due to a disease involving the swim bladder, an organ responsible for the fish’s buoyancy. However, mollies will also swim up and down when they are pregnant, bullied, or when the aquarium conditions are inadequate.
How many mollies should be kept together
Mollies tend to stick together most of the time, which is why you should keep them in groups of 4 or more. If you are planning to keep more than 4 mollies, make sure you get a 20-gallon tank at least. A 45- gallon tank should be a perfect choice if you plan to manage multiple shoals of mollies.
Why are my mollies chasing each other
The reasons why Molly fish will chase each other and seem aggressive has to do mostly with mating rituals that involve attention-seeking behavior. This is when a male molly chases a female molly or aggressively fights off the other male mollies in the tank.
Will my Molly fry survive
The only sure fire way fry will survive is to separate mom into her own tank with water from her big tank until she releases the fry, then take mom out. I never had much luck with any fry surviving in a community tank.
Can swim bladder cure itself
Depending on the cause, swim bladder disorders may be temporary or permanent. If your fish has a permanent swim bladder disorder, they can still live a full and happy life with some lifestyle modifications.
Can Mollies change gender
They can’t change sex but some males will mature later then others so will appear female for a time. The top one does look as if it could be a late developing male. I’ve kept mollies for 2 years and have had many late developing males.
How do I keep my molly fish happy
Sandy substrate is recommended just so you can keep vegetation in your tank. To keep them happy, give these little fish with big personalities with things to do like tall plants to hide between. Satisfy their natural curiosity with artificial caves and rocks to explore.
How do you cross breed a Molly
Only breed male guppies to female mollies. The size of the fry will kill the female when she is giving birth, if the female is the guppy. Also, make sure that you have 1 male guppy to 4 female mollies ratio in your tank. And do not try to sell or give them away as a pure breed.
Why do fish raise their dorsal fin
Dorsal fins are located on the back. A fish can have up to three dorsal fins. The dorsal fins serve to protect the fish against rolling, and assist it in sudden turns and stops. In anglerfish, the anterior of the dorsal fin is modified into an illicium and esca, a biological equivalent to a fishing rod and lure.
What is the lifespan of a molly fish
around three to five yearsThe average molly fish lifespan is around three to five years.
Do Mollies swim at top of the tank
Molly fish typically swim and stay at the top of the tank due to a swim bladder disease, secondary to constipation and overfeeding. The condition disturbs the fish’s buoyancy, forcing it to float. However, mollies also frequent the top sections due to oxygen deficiencies and elevated toxins.
Why is my molly fish sitting at the bottom of the tank
They are essential to protect your fish from high ammonia and nitrite during a cycle. The bacteria you are trying to establish fixes itself to surfaces in your tank and filter. The number of them in the water is minuscule so water changes don’t effect their numbers. Did you read the links?
