黑幻燈魚

關於黑幻燈魚

A small characin with a black shoulder patch on a grayish-brown body. Males grow long black fins while females show a reddish tint and deeper body. Calm, shoaling, and easy for beginners to keep.

迎接黑幻燈魚前需要了解的7件事

1. 1Keep Them in a Shoal

   Kept alone or in pairs, they tend to stay skittish and hide rather than show their natural behavior. Males only display their fin-spreading rivalry once kept in a proper shoal of eight or more.

2. 2Telling Males from Females

   Males develop noticeably long, flowing black fins, while females are deeper-bodied with a soft red tint on the ventral, anal, and adipose fins. Knowing this difference makes it easier to balance the sexes when choosing a group.

3. 3A Small Species, Max 3.6 cm

   Adults reach only about 3.6 cm at most, so a small to medium tank can comfortably house a group of them. Their compact size also makes them easy to pair with other peaceful fish of similar scale.

4. 4Peaceful, Good for Community Tanks

   Their calm temperament means they rarely chase or harass other fish, so they mix well with similarly sized, peaceful tankmates. That said, very small fry or tiny shrimp can be seen as food, so choose tankmates with that in mind.

5. 5Pairs Well with Planted Tanks

   Their muted grayish-brown coloring stands out beautifully against a planted layout. Since they also like to retreat into cover, adding floating plants, driftwood, or dense planting gives them places to feel secure.

6. 6Beginner-Friendly to Keep

   They're generally rated as easy to keep and hold up well for less experienced fishkeepers. Even so, they're sensitive to sudden shifts in water quality or temperature, so take your time acclimating new arrivals.

7. 7Set Up the Tank First

   Since they do best in a shoal, it's worth setting up a tank with adequate water volume and filtration and letting the water stabilize before adding fish. Introducing a large group all at once can strain water quality, so adding them gradually is also a good option.
