概述
侣兵鲶(Brochis sodalis)是温和的群居鼠鱼,适合与小型安静鱼类相处。它会在底部找食物,但不能代替吸污和换水,也不应只靠其他鱼漏下来的残饵生活。
分布与栖息地
来自亚马孙河上游的秘鲁洛雷托省和巴西亚马孙州,生活在小支流、溪流、水潭以及被洪水淹没的森林区域。
饲养环境
细砂、沉木、树根和干燥落叶可营造昏暗的亚马孙环境,木材与叶片释放的物质会使水略呈茶色。定期更换老化落叶,避免腐败积污;原生水域少见水草,但缸中也能采用有密植区域的普通草缸布置。它对水质恶化敏感,需要规律维护,特别是底部清洁;不宜采用底滤板过滤。
食性与喂食
属于杂食鱼,可用优质下沉颗粒或片状底栖饲料为主,配合水蚤、丰年虾、红虫等活饵或冷冻饵。投喂须有专门到达底部的份额,不能把它当作清理残饵的工具鱼。
习性与混养
至少六条同养更自在。小型灯鱼、温和鲤科鱼、迷鳃鱼和合适的小型慈鲷都是可考虑的同伴,避开大鱼和攻击性种类。性情温和并不代表不会吃入口的小卵或鱼苗。
雌雄区分
俯视时雌鱼腹部更圆、体形更宽,通常也略大,怀卵后尤其明显。
繁殖
可采用鼠鱼常用的繁殖方式:独立缸放少量莫丝等附卵物,使用气动过滤,配合软水与充氧。雄鱼数量多于雌鱼,常以两雄配一雌,先用多样食物养好状态。雌鱼明显怀卵后,可通过较凉的新水与增加水流刺激产卵;反应还受成熟度和季节影响。
求偶时雄鱼追逐雌鱼,形成丁字形姿势后,雌鱼用腹鳍暂托少量卵,再将其黏在玻璃等表面。产后移走成鱼或单独孵卵,水质保持一致且充氧良好,及时清除发霉的卵。通常约三至五天孵化,鱼苗消耗卵黄后可吃微虫和丰年虾无节幼体。薄砂底育苗可能比完全裸底更有利,但仍须勤于清洁。
补充说明
偶尔冲到水面吞气是利用肠道辅助呼吸的正常行为;若频率明显上升,应检查水质和供氧。胸鳍硬刺容易挂网,捞取时需避免纠缠与刺伤。

English
Overview
Brochis sodalis is a gentle cory that benefits from living with its own kind. It makes a suitable companion for many small community fishes, provided clean conditions and a dedicated food ration are maintained. Bottom foraging does not replace aquarium maintenance.
Distribution & habitat
Its upper Amazon range includes Loreto in Peru and Amazonas state in Brazil. Small tributaries, creeks, pools, and seasonally flooded forest provide habitat.
Aquarium setup
Sand, branching wood, roots, and dried leaves create a sheltered setting under subdued light. Tannins can give the water a pale tea tint. Replace aging leaves before excessive decay fouls the aquarium. Although aquatic plants are not characteristic of its native waters, planted aquariums also work. Avoid undergravel filtration and maintain a particularly clean floor; declining conditions can lead to barbel problems.
Diet & feeding
An omnivore, it takes sinking pellets or tablets supplemented with live and frozen foods such as water fleas, brine shrimp, and bloodworms. Deliberately provide food for the group instead of expecting it to survive on leftovers.
Behaviour & compatibility
Keep at least six together. Small characins, gentle cyprinids, labyrinth fishes, suitable dwarf cichlids, and peaceful catfishes can share the aquarium. Avoid large or aggressive companions. Eggs and tiny fry may still be eaten despite its generally nonaggressive temperament.
Sexual dimorphism
Females are usually slightly larger and appear distinctly fuller when viewed from above, especially before spawning.
Breeding
Prepare a separate aquarium with spawning cover and air-powered filtration. Soft water and strong aeration are useful. A male-biased group, often two males per female, can be conditioned on varied foods. Cooler replacement water and additional circulation may trigger ripe fish, though maturity and seasonal timing affect results.
Courtship includes pursuit and the characteristic T-shaped pairing posture. Females briefly hold a few eggs between the pelvic fins before attaching them to glass or another chosen surface. Remove adults afterward or transfer eggs to matching, oxygenated water. Discard fungused eggs promptly. Hatching generally takes three to five days; after yolk absorption, offer microworms or newly hatched brine shrimp. A shallow sand layer may benefit fry compared with a completely bare floor, without reducing the need for cleanliness.
Notes
Occasional surface gulps are part of intestinal air breathing. A marked increase warrants checking oxygen and water quality. Sharp pectoral spines can catch in nets or puncture skin, so move fish carefully.
