Molly Fish Types: Every Color & Fin Variety Explained
Published: 2026-09-16 · FishyKart Blog
Every Molly fish sold in the hobby is a variation on the same handful of traits — body color/pattern, body shape, and fin type — mixed and matched across breeding lines. Once you separate those three traits, the dozens of trade names ("Dalmatian Lyretail," "Golden Sailfin Balloon") stop being confusing and just describe a specific combination. This guide breaks down each trait on its own.

Color & Pattern
| Type | Description |
|---|---|
| Black | Solid jet-black, most common variety |
| White | Creamy-white body, often pink/red eyes |
| Dalmatian | White base with irregular black spots |
| Chocolate | Deep brown to copper body tone |
| Gold Dust / Creamsicle | Orange-yellow with metallic gold sheen |
Body Shape: Standard vs Balloon
Most colour varieties above come in a standard torpedo-shaped body. A separate "Balloon" line breeds for a shortened spine that gives a rounded, compressed body — it's a shape modification, not a colour, so you'll see "Balloon Black Molly" and "Balloon Dalmatian Molly" as distinct combinations. Balloon-bodied fish swim less efficiently and need calmer tankmates; see the dedicated Balloon Molly guide for the health trade-offs of this shape before choosing one.
Fin Type: Short-fin, Sailfin & Lyretail
- Short-fin (standard) — the default fin shape on most Black, White, Dalmatian and Chocolate Mollies
- Sailfin — not just a bigger fin: Poecilia latipinna is a genuinely different, larger species, and only males grow the tall sail-like dorsal. Needs a bigger tank (30+ gallons) than common Mollies
- Lyretail — an extended, forked tail fin that can be bred onto almost any colour/body combination above; it's a tail-shape trait layered on top of the others, not a species or colour of its own
Putting It Together
A shop listing like "Black Lyretail Molly" or "Gold Dust Sailfin" is just naming the colour and the fin trait together — there's no separate "Lyretail species" to look up. When comparing two Mollies that look different, it usually comes down to which of these three independent traits (colour, body shape, fin shape) differs between them, not a difference in underlying care needs — the core care requirements stay the same across nearly all of them, with Sailfin and Balloon being the two exceptions worth planning around.
