Overview
The Black Moor is the velvet fancy - a matte-black telescope-eyed goldfish whose protruding eyes and dark colour make it one of the most recognisable (and most forgiving) of the odd-bodied breeds. Poor eyesight and gentle nature ask for a calm, smooth-decorated tank and considerate feeding.
Natural History
A black telescope line fixed in China and beloved for centuries; 'Moor' from the deep black. One of the few fancies that keeps its colour reliably (mostly).
Appearance
Egg body 15-20 cm with protruding telescope eyes and flowing fins in velvet black; deep black can bronze with age or warm water - normal, if slightly heartbreaking.
Tank Size & Setup
75-100+ liters, SMOOTH everything (those eyes snag and injure), gentle flow, no sharp plastic plants; tankmates limited to equally slow, gentle fancies - ideally other telescopes.
Water Parameters
18-23°C, clean and stable; standard fancy care with extra points for consistency.
Diet
Sinking food placed consistently in one spot - they find dinner by smell and memory more than sight; make it easy and they thrive.
Health & Lifespan
Average lifespan is 10-15 years. Sturdy for an extreme fancy: 10-15 years commonly. Eye injuries and the usual swim-bladder notes are the watch-list.
Pros & Cons

- Hardier than most odd-eyed breeds
- Sweet, placid temperament
- Classic and affordable
Cons
- Near-sighted - loses feeding races
- Eyes vulnerable to sharp decor

Black Moor Goldfish - frequently asked questions
Why is my Black Moor turning orange?
Age, warm water and genetics can bronze the black - it's cosmetic, common, and not illness. Cooler water and good light slow it.
Can they see at all?
Poorly - movement and shadows mostly. They navigate by smell and habit, which is why stable decor and consistent feeding spots matter.
Best tankmates?
Other telescopes and gentle fancies (Fantails, Orandas). Never singles, never fin-nippers, never anything that races them to food.
