概述
瓦氏旗鮰（Fundulopanchax walkeri）是一种会捕食可吞下小鱼的鳉鱼，性情也相对强势，单养更便于照顾。它偏好较凉水温，过热会明显缩短寿命，不能照搬其他热带鳉鱼的加温习惯。
分布与栖息地
来自科特迪瓦和加纳，栖息沿海雨林及林地草原中的溪流、沼泽和水池。部分野生种群因人类开发而受威胁，甚至消失。它似乎既有周年型也有非周年型，可利用临时和永久水体。
饲养环境
日常饲养可参考 45 × 25 × 25 厘米的空间。深色底床、密植水草和沉木提供躲藏点，浮水植物遮阴，泥炭过滤可作为选择。它善跳，缸盖需贴合严密。
食性与喂食
偏好水蚤、红虫等小型活饵或冷冻饵，许多个体也能接受优质薄片。即使平时规律投喂，仍不能把能被吞下的小鱼视为安全伙伴。
习性与混养
虽可谨慎混养，但更推荐单养。小鱼有被吞食风险，它本身也较有攻击性，水温需求同样会限制伙伴选择。
雌雄区分
雄鱼较大，色彩更鲜艳。
繁殖
先将雌雄分开，以多样活冷冻饵调养，再选一雄两雌繁殖。卵可产在底床或植丛中，泥炭、莫丝和拖把均可使用，裸底配拖把较方便收卵。繁殖缸无需强光，温和海绵过滤即可。
可连续多日产卵，每日约 10–30 枚，但约一周后应让亲鱼回调养缸恢复。想提高数量宜移卵孵化，避免部分卵苗被吃。水孵时保持避光，定期剔除发霉卵，通常约 21 天孵化；湿泥炭法可约储存 8–12 周后加水促孵，各容器标注血系、日期和卵数。
鱼苗可用丰年虾无节幼体或微虫开口，起初水浅，随成长逐渐加深；约两周后可换较大的活饵和冷冻饵。

Overview
Predatory and assertive, Fundulopanchax walkeri is most conveniently maintained in a species tank. It swallows fishes that fit its mouth and favors cooler conditions than many killifishes; excessive warmth can substantially shorten its life.
Distribution & habitat
Native to Ivory Coast and Ghana, it occupies streams, swamps, and ponds in coastal forest and wooded savanna. Development has threatened or eliminated some populations. Apparently both annual and nonannual forms occur, allowing use of temporary as well as permanent water.
Aquarium setup
A 45 by 25 by 25 cm aquarium is the maintenance reference. Combine dark substrate, dense plants, wood, and floating shade. Peat filtration is an option, and a tightly fitted lid is essential for this strong jumper.
Diet & feeding
Small live and frozen foods are favored, with quality flakes accepted by many individuals. Regular feeding does not make smaller fishes safe companions.
Behaviour & compatibility
A community is possible only with careful choices; a species aquarium is preferable. Predation, assertive behavior, and cooler water requirements all restrict compatible tankmates.
Sexual dimorphism
Males grow larger and show brighter coloration.
Breeding
Condition males and females separately with varied live and frozen foods, then introduce a trio. Eggs can be deposited in substrate or vegetation; peat, moss, and mops all work. Bare-bottom tanks with mops simplify collection, and only gentle filtration is needed.
Daily batches may contain about 10–30 eggs. Return breeders to conditioning after roughly a week rather than exhausting them through extended spawning. Remove eggs for better yield. Keep water-incubated eggs dark, discarding fungal ones; hatching typically takes about 21 days. Damp-peat incubation can last around 8–12 weeks before wetting. Label containers clearly with line, dates, and egg counts.
Fry begin on Artemia nauplii or microworms in shallow water. Increase depth and introduce larger foods progressively, with larger live or frozen items possible after about two weeks.
