概述

L076 是尚未以正式种名确定的 Peckoltia 异型鱼,在洞中产卵并由雄鱼照料后代。它与另一个贸易编号可能对应同种,不能仅凭白天体色深浅就认定是两种鱼。

分布与栖息地

据称采自巴西北部帕拉州波特尔一带的帕拉河。帕拉河属于亚马孙河口南侧水道,绕过马拉若岛的西侧和南侧。

饲养环境

应从缸长至少 120 cm 的底面积考虑,给成鱼留下充分空间;繁殖还需要可使用的洞穴。

雌雄区分

成年雄鱼尾柄具有齿状突起,雌鱼没有这一特征。

繁殖

在洞穴内产卵,后续育幼由雄鱼负责。

补充说明

L076 与 L099 似乎是同一种。白天前者通常较暗,夜间两者却显得接近,因此观察时间可能影响外观判断。

Overview

L076 is an unnamed Peckoltia that spawns in caves, with males caring for the brood. It may represent the same species as another trade number, so differences in daytime darkness do not necessarily establish separate species.

Distribution & habitat

Collections are reported from the Pará River near Portel in northern Brazil. This channel forms the southern arm of the Amazon mouth, passing around the western and southern sides of Marajó Island.

Aquarium setup

Consider an aquarium at least 120 cm long, with sufficient floor space for adults and a usable cave for spawning.

Sexual dimorphism

Adult males develop odontodes on the caudal peduncle; females lack this feature.

Breeding

Eggs are laid in a cave, and the male assumes brood care.

Notes

L076 and L099 appear to be the same species. The former is darker by day, whereas both look similar at night, making observation time relevant to visual comparison.
