寿命

资料稀少

体型

标准体长 最大3.8厘米（FishBase）

适宜温度

22〜26℃

饮食

杂食（沉底型人工饲料、冷冻饲料）

水温和水质

水温22-26℃，pH6.0-8.0（FishBase）。Seriously Fish的数据为21-27℃，pH5.6-7.0，硬度0-12dH。对水质恶化敏感，因此需要定期换水。

水族箱

底床应使用河砂等圆角细砂，不使用底部过滤。脏污的底床会损伤胡须，因此需要经常清理底部。加入沉木或落叶可以创造更自然的环境。

混养和相容性

性格非常温和，可与小型脂鲤、鲤科鱼、丝足鱼科鱼、矮慈鲷等混养。不适合与大型鱼或攻击性鱼类混养。成群饲养6条或以上时，活动活跃且稳定。

饲料和投饲

杂食，容易驯饲。以沉底型片剂和颗粒饲料为主食，辅以水蚤、丰年虾、血虫等冷冻饲料或活食。

繁殖和产卵

据说2条雄鱼配1条雌鱼的比例较好。当雌鱼腹部因卵而膨胀时，采用低温水进行50-70%的换水可促进产卵。卵通常产在玻璃面等地方。

健康和注意事项

因为学名已更改为Hoplisoma simile，所以图鉴和销售标签上通常会同时标注旧名Corydoras similis。

关于相似鼠鱼

Smudge spot cory (Corydoras similis): a small, peaceful, schooling corydoras from Brazil's Madeira River system, with fine spots and a dark smudge near the dorsal fin. Up to 3.8 cm standard length and beginner-friendly.

迎接相似鼠鱼前需要了解的7件事

1. 1Keep them in a group

   The Smudge spot cory is a peaceful fish that prefers company. A single fish may seem uneasy and hide more often, so keeping several together makes it easier to see their natural schooling behavior.

2. 2Floor space matters

   With a maximum standard length of 3.8 cm, this is a small fish that spends much of its time near the bottom. When choosing a tank, think about floor area rather than height so that a group has room to roam and settle in comfortably.

3. 3Choose fine substrate

   Corydoras use their barbels to search the bottom for food. Fine sand or smooth, rounded substrate is gentler on the barbels and mouth, so it is safest to avoid sharp, jagged gravel.

4. 4Choose calm tank mates

   Because it is peaceful, it pairs well with other calm, small fish. Its small size, however, means you should avoid aggressive or large fish, and any fish big enough to swallow it.

5. 5Feed food that sinks

   Since it looks for food mainly on the tank floor, sinking prepared foods suit it well. Other fish may finish the food first, so watch to make sure enough reaches the bottom.

6. 6Water changes and daily checks

   Fish are more likely to become unwell in dirty water, so regular water changes to keep the tank clean are the basis of good care. If a fish looks listless or stays motionless on the bottom, take it as a cue to review water quality. If you use a fish medication, read the instructions carefully, as precautions differ by product.

7. 7Acclimation and hiding spots

   A sudden change of environment is stressful right after arrival, so take your time acclimating the fish to the new water. Adding driftwood or rocks as hiding places can help them settle into the new tank.
