Black Molly - General Care

The Short-Finned Molly needs a tank of least 30 gallons with plenty of tough plants such as Java Fern, Sagittaria, Vallisneria, or Anubias. Mollies have a taste for plants and will destroy softer-leaved plants.

Black Molly
The Black Molly is a short-finned hybrid variation of Poecilia latipinna, the Sailfin Molly. The Black Molly is all black in coloration with short fins. They may have patches of a slight gold or silver coloration when a juvenile, but will outgrow this with age.

Pictured is the ~. These livebearers like some aquarium salt in the water and will give lots of fish babies. Be responsible and only breed them if you have a plan for what to do with all the fry.
Another popular freshwater aquarium fish species and a very hardy livebearer.

The color is highly variable ranging from the ~ to orange and blue forms. The feral form has an olive-green back and bluish flanks. The flanks are spotted with orange spots, and the belly region is orange. The iris of the eye is blue. The fins are brownish.
SIZE : Females to 4.

There are many species of mollies, including the ~, sailfin molly, balloon molly and silver molly. Mollies are not freshwater fish, but brackish fish meaning they require a small salt concentration in their habitat. Add a teaspoon of freshwater aquarium salt every water change.

This species is one of the ancestors of the ~, a melanistic breed which is black all over. It is one of the most well-known aquarium fishes and nearly as easy to keep and prolific as guppies (for optimal health and breeding success, they demand fresh vegetable food like algae).

One day my boyfriend and I bought this absolutely beautiful ~ to add to my always-growing aquarium. Little did I know just how quickly it was growing when we awoke the next morning to see, not just one molly, but 30! ...

~ (Poecilia shenops). The fascinating thing about Black Mollies is that they are from brackish waters so you can actually keep them in both freshwater and saltwater tanks! Black Mollies are live-bearers but they don't take care of the fry.
Platy (Xiphophorus maculatus).

Livebearers such as the ~ , Sword Tail , and Platies are not the best choice for a first time aquarium. Reason ? : They are short lived and they are usually raised in outdoor ponds and sometimes shipped with diseases and parasites.

Common Mollies are the ~ (which was derived from the Marled Molly - Poecilia sphenops) and the Sail-Fin Molly - Poecilia velifera (of which there are also several color varieties available).

Dalmatian Molly (silver or white base with irregular black spotting), Jet ~ or Midnight Molly (same shape and size as a sailfin, but solid jet black coloring), Standard Sailfin (can come in a wide range of colors of grey, orange, red, yellow, violet, and some times various combinations).

I once raised a batch of ~ fry, dividing them evenly between the seven-gallon tank and a standard 20-gallon long. The fry in the smaller tank grew at approximately twice the rate. The fry in the 20-gallon had to use a large portion of their energy to feed in the larger aquarium.

The wild form is a silvery grey colour but the most popular type in the aquarium trade is the ~. Mollies can be aggressive towards other fish so care should be taken when choosing tank mates.

Zebrasoma rostratum, Psydochromis friedmani, Centropyge loriculus, Calloplesiops altivelis and one ~ blennie.

Contains two furan compounds to combat a wide variety of gram positive and gram negative bacterial diseases, including gill disease, mouth fungus, furunculosis (aeromonas), ~ disease (columnaris), fin and tail rot and dropsy.

The tank should not however be routinely salted if it is a mixed community containing soft water fishes.
Many colour varieties are available - including silver, mottled and speckled or "dalmation" varieties, and the popular ~.

The base of the tail is colored in ultramarine blue; in the upper part it is orange-yellow with a black hem. There are other color varieties; one of them is the ~. Beside the normal tail variety, there is a lyre tail variety. The optimal temperature is 24-28 C.

(I will probably also need some stuff for buffering the water.) Fish: I will probably use ~2 ~s to cycle this tank as well as deal with the initial algae growth.
