Mollie Fish Species Profile

The genus mollie or mollienesia, as it have become at the start labeled, has some of the most cute and unusual sorts of live-bearer fish. The sailfin mollie is arguably one of the maximum uncommon fish available of any genus. but, mollies are possibly the maximum hard of all of the now not unusualplace stay-bearers to hold as they may be the most sensitive of the live-bearers. when chilled or otherwise exposed to environmental pressure of any type, they have a tendency to boom an ailment recognized usually as “shimmies.” In fact, this is not an infectious disease but truly a compounding of signs and symptoms of strain.

medical call: Poecilia sp.

person length: four inches

Origin and Distribution

Mollies are specifically determined from Southern america down into significant america.1 The neighborhood habitat of these fish extends from the southern united states to the Yucatan peninsula in Mexico, and that they thrive specially in freshwater environments, once in a while venturing into brackish estuaries. Mollies, like guppies, are able to acclimating to complete strength sea water quickly, but it isn't always their natural environment thru any manner.

The genus Mollienesia, from which the call mollie became derived, has been re-labeled as Poecilia and is taken into consideration to be withinside the equal genus because the guppy. For years it were found that the guppy will, under sure occasions, interbreed with the mollie, and the near courting a number of the 2 has been confirmed genetically.

Colors and Markings

All captive mollie species had been interbred over centuries, resulting in masses of specific shadeation types and fin shapes.1 solid black mollies and sail fin kinds with orange-bordered dorsal fins are not unusualplace sorts. No different freshwater fish methods the velvety black shadeation of the black mollie. There are also albino office work with crimson eyes, authentic lyre tails in most every shadeation, or even chocolate, gold dust and orange types.

Diet and Feeding

In nature mollies are almost totally plant and algae eaters, in order that they have to be fed lots of spirulina, even boiled spinach finely chopped, to live healthful.2 if your tank lacks algae, you should offer “spirulina” flakes, unique commercial Mollie food, or small quantities of chopped boiled spinach. They revel in consuming algae growth withinside the aquarium, and will graze with no end in sight on it, seeking out desire patches to nibble.

Sail fin Mollies are available in severa shadeation sorts. even though the ones fish breed effectively, more youthful raised in tanks not often increase the “sail fin” and actually handiest gain approximately three-31/2 inches in period. but raised in a again backyard pond, remarkable, jeweled sail fins will seem at about 4 months.

Gender Differences

simplest grownup males have the “sail fin” and withinside the wild, can increase as lots as five inches long

In most live-bearers, the pregnant mom swells unmistakably and moreover gives the properly-regarded “gravid spot” that could be a dark spot near the lowest of the anal fin because of the stretching of the peritoneal wall. The woman has a everyday-shaped anal fin.​

barely beforehand of this, internal her frame appears a dark region that is known as the gravid spot. it's far, in reality, same to the womb, however no longer like mammals, the egg isn't always related to the mom’s body and fed thru her at once.

each egg consists of an embryo and is well furnished with nutritive factors, furnished thru the mother's machine, on which the developing embryo feeds at some point of its development. however, today's research show that there can be a symbiotic dating many of the mother and the developing fry with an exchange of fluids, the overall volume if which is still below investigation.
