Mollys like a temperature of around 72F, slightly salty water, plenty of algae around to nibble on and heaps of room to swim and grow in. They are mainly vegetarians but enjoy live foods like daphnia and mosquito larvae too. Your local pet shop may even stock special Molly food.
Provided the fish is given proper food and good conditions, yes the fins will grow back. The new fin(s) are never as perfect as the old ones. There is usually some deformity (scarring) resulting from the damage.
depends what species a molly fish fry
I'm assuming you are sking how long a Molly carries her young inside her for. If that is what you wish to know then the answer is "It varies depending on the conditions she is kept in. A female Molly (Poecillia sp) usually carries young for 3 to 4 weeks but they have been known to extend this period for several months when conditions are bad.
I can almost guarantee that they will have young provided they are in conditions that suit them. Mollies grow to around 3 inches so a minimum sized tank for a pair of mollies if you want them to breed would be a nominal 15 gallon tank. You would also need the tank to be heated, filtered, planted and lit with proper lights to help the plants grow.
Mollies take about 6 months to reach sexual maturity.
Yes, a black Molly is a breed of fish in the breed "Molly". They grow up to about two and three-fourths inches from head to tail. These fish are a community breed so you can mix them with other community fish. They come from Central America.
This is a great question! Algae does not grow on healthy fish. What you may be witnessing is the molly nipping at other fish as a territorial aggression. They can also nip or taste another fishes slime if they like it too. You may want to make sure your aquarium has plenty of cover and places to hide.
No. Many fish in the dark still grow, but it would be good to give light once in a while.
Heck yes. Dead fish are good fertilizer.
Yes it is quite possible provided it is kept in reasonably good conditions and fed a reasonably good diet its damaged fin could well grow back
The size of a fish tank can affect the growth of fish because it impacts their living conditions and ability to move freely. Fish do not necessarily grow to the size of their tank, but a larger tank can provide more space for them to grow properly and reach their full potential size.
Yes, it's advisable to separate a pregnant balloon belly molly from the other fish in the tank, especially as she approaches her due date. This helps reduce stress for the pregnant fish and increases the chances of survival for the fry, as adult fish may eat the newborns. Providing a separate breeding tank allows for a safer environment for the fry to grow.
