概述

施瓦茨氏兵鲶(Hoplisoma schwartzi)是普鲁斯河流域的温和群居甲鲶,水温宜约 22~24 °C。可以人工繁殖,但诱发产卵较难,需要耐心观察成熟状态与环境。

分布与栖息地

巴西普鲁斯河流域特有,生活于小支流、溪流、淹水森林和沙洲。

饲养环境

小群可参考约 60 × 38 × 30 厘米。细沙、沉木枝、根部与干落叶配较暗光线,落叶定期换新以免污染;也可采用维护良好的水草缸。底床洁净十分重要,不用底滤板,避免触须受损。

食性与喂食

杂食,优质下沉颗粒或片剂为主,补水蚤、丰年虾、红虫等活冷冻饵,主动保证食量。

习性与混养

至少六尾共同饲养,更容易自信活跃。避开很大或攻击性伙伴,选择适应相同条件的温和小鱼或鲶鱼。

雌雄区分

雌鱼往往略大,从上方看更宽圆,抱卵时尤其明显。

繁殖

一雌两雄,海绵过滤与细叶植物,参考水温 24 °C、酸碱度 6.5。用多样饵料调理,抱卵后尝试偏凉水换 50%~70% 并增氧。若一直不产,可调整换水时机等条件;使用其他刚产卵鼠鱼的缸水诱导也仅是有人提出的方法,化学信号解释尚属推测。卵黏在玻璃等处,产后分开亲鱼与卵,充氧孵化并除霉卵。通常三至五天孵化,卵黄吸收后喂微虫或初孵丰年虾,薄沙底似有利。

补充说明

偶尔吞气可辅助呼吸,明显增频时应检查水质。胸鳍硬棘易挂网和刺伤皮肤,转移需小心。

Overview

A peaceful Purus-basin catfish, Hoplisoma schwartzi is suited to about 22–24 °C. Captive spawning is possible, although triggering it can be difficult and may require patience.

Distribution & habitat

It is endemic to Brazil’s Purus drainage, using small tributaries, creeks, flooded forest, and sandy banks.

Aquarium setup

A suggested setup for a small group measures about 60 by 38 by 30 cm. Sand, branches, roots, and leaves under subdued lighting work well, as can a carefully maintained planted tank. Replace aging leaves and maintain clean substrate. Avoid undergravel filtration to protect the barbels.

Diet & feeding

Provide sinking pellets or tablets with varied small live or frozen supplements. This omnivore needs direct feeding rather than community scraps.

Behaviour & compatibility

Keep at least six and choose calm companions of compatible size and water requirements. Large or aggressive fishes are unsuitable.

Sexual dimorphism

Females are often slightly larger and broader, best compared from above when gravid.

Breeding

Use two males per female, sponge filtration, and fine plants around 24 °C and pH 6.5. Condition the fish well, then try a 50–70% cooler-water change with added aeration when females are gravid. Timing and other conditions may need adjustment. Water from a recently spawning cory tank has been suggested as another trigger, but its proposed chemical-signaling mechanism remains hypothetical. Separate adhesive eggs from adults and incubate with good oxygenation, removing fungal eggs. Hatching normally takes three to five days, followed by small live foods after yolk absorption. Thin sand appears useful for rearing.

Notes

Occasional surface gulps supplement respiration; an unusual increase warrants a water-quality check. Take care with pectoral spines, which can snag netting or puncture skin.
