概述
Betta pallida 是小型雄性口孵斗鱼，头和身体偏黄，体侧有纵纹。虽然颜色不如人工斗鱼张扬，安静、遮蔽充足的环境更能观察其配对和育幼行为。
分布与栖息地
目前已知记录在泰国半岛最南端的那拉提瓦。采集溪流浅而缓，水清澈、略带单宁染色，底部铺着落叶。
饲养环境
一对或小群至少需要约 60 × 30 cm 的缸底面积。沉木、枝条、陶盆和短管可提供阴暗藏身处，落叶增加遮蔽并滋养微生物，裸底方便维护。
以弱光配耐阴水草和浮水植物，成熟海绵过滤温和循环即可。缸盖防跳，同时留出水面潮湿空气层及上浮呼吸空间。
食性与喂食
野外可能捕食昆虫、小型无脊椎动物和浮游动物。缸养通常能适应干粮，仍需定期搭配水蚤、丰年虾、红虫等活饵或冷冻饵；小昆虫先喂饱再投喂。控制份量，避免过肥。
习性与混养
可成对或组群，但更适合单种缸，或与极温和且条件相近的伙伴相处。大型、活跃及抢食强的鱼容易压制它，混养要确认每尾都能正常活动进食。
雌雄区分
雄鱼通常较大，头较宽，头部亮鳞更多，鳍的延伸也更明显。
繁殖
反复缠抱后分批排卵，卵先由雄鱼臀鳍承接，雌鱼拾起再吐给雄鱼含入口中。雄鱼口孵约 9～12 天后，释放能自由游动的鱼苗。
受惊或缺乏经验可导致吞卵或提前吐卵，通常宜让雌鱼和其他鱼留在原位，减少捕捞干扰。鱼苗可另养或随亲鱼成长，后者生长更快的说法仅有部分经验支持。
水面空气需温暖潮湿，帮助鱼苗迷鳃发育。初期可喂微虫和丰年虾无节幼体，每天少量、多样喂 2～3 次，避免过量单一使用丰年虾，并规律少量换水。
补充说明
曾以 Betta sp. ‘southern Thailand’ 的代号流通。连续的中央暗纵纹、下方纵纹后段分解成小斑，以及尾柄无斑等特征可辅助辨认。

Overview
Betta pallida is a small paternal mouthbrooder with yellowish coloration and longitudinal flank markings. A quiet, sheltered aquarium provides the opportunity to observe pairing and parental behavior without pressure from busy companions.
Distribution & habitat
Known records are confined to Narathiwat at the southern end of Peninsular Thailand. Collection sites include shallow, slowly flowing creeks with clear, slightly tannin-stained water and leaf-covered beds.
Aquarium setup
Allow at least a 60 × 30 cm footprint for a pair or small group. Wood, branches, pots, and tubes create shaded retreats. Leaves add shelter and microbial growth, while a bare floor can make cleaning easier.
Use subdued light, suitable plants, floating cover, and gentle mature sponge filtration. Fit a secure lid against jumping while retaining humid air above the water and access for breathing.
Diet & feeding
Insects, small invertebrates, and zooplankton are thought to be natural prey. Captive fish generally learn to take dry food, supplemented with water fleas, Artemia, bloodworms, and other live or frozen items. Small feeder insects can be fed beforehand. Avoid excessive portions.
Behaviour & compatibility
Pairs and groups are possible, but dedicated accommodation or exceptionally gentle companions with matching requirements is preferable. Large, active, or competitive feeders can suppress it. Ensure every individual remains active and obtains food.
Sexual dimorphism
Males usually grow larger and broader-headed, with more head iridescence and longer fins.
Breeding
Repeated embraces release eggs onto the male's anal fin. The female retrieves and passes them to him, and he eventually carries the entire brood. Swimming fry are released after approximately 9–12 days.
Stress or inexperience can cause swallowing or premature release. Leaving the female and other fish undisturbed avoids disruption from catching them. Young may be raised separately or with parents; reports of faster growth beside adults remain individual observations.
Maintain warm, humid nursery air for labyrinth development. Microworms and Artemia nauplii are suitable first foods. Offer varied small meals two or three times daily without overusing the latter, and replace modest amounts of water regularly.
Notes
The former trade designation was Betta sp. ‘southern Thailand’. An uninterrupted central stripe, a lower stripe breaking into posterior blotches, and absence of a tail-base spot help identification.
