迎接感嘆号小鱼（Boraras urophthalmoides）前需要了解的7件事

1. 1Prefers Soft, Acidic Water

   In the wild these fish live in the peat swamps and marshes of Southeast Asia, so they thrive in soft, weakly acidic water. Filtering through soil substrate or peat helps keep water chemistry stable.

2. 2A Natural Shoaling Fish

   Kept in a group rather than alone, this rasbora shows more of its natural behavior and its tiny body looks far more lively. Shoaling together is also thought to reduce stress.

3. 3The "Exclamation Mark" Pattern

   The dark stripe along the body paired with the round black spot at the base of the tail resembles an exclamation mark — the source of both its English and Japanese names. It's also a useful clue for telling it apart from closely related Boraras species.

4. 4Choose Small, Peaceful Tankmates

   Because this fish is extremely small, avoid housing it with large or aggressive species and stick to similarly sized, peaceful tankmates. It also tends to do well alongside invertebrates such as shrimp.

5. 5Feed Fine, Small Food

   Its mouth is very small, so powdered or finely crushed food is easiest for it to eat without leftovers. Offering small amounts several times a day helps ensure even nutrition.

6. 6Sensitive to Sudden Water Changes

   Being so small, this fish is sensitive to sudden shifts in water quality or pH. Take time acclimating new arrivals, and change water in small, frequent amounts rather than large infrequent ones.

7. 7Why It's Rated for Intermediate Keepers

   Maintaining stable, soft, weakly acidic water and staying alert to changes in water quality are what place this species in the intermediate category. It helps to understand the basics of water management before bringing one home.

Q.Is this fish suitable for beginners?

A.This species is generally rated for intermediate keepers, so some prior experience with water quality management is recommended. Beginners who can maintain stable, soft, weakly acidic water can still succeed with it.

Q.Can it be kept with other fish?

A.Because it's so small, it does best with similarly sized, peaceful tankmates. Avoid pairing it with large or aggressive fish.

Q.What tank size does it need?

A.With a standard length of around 1.6 cm, this is an extremely small fish best kept in a group, so choose a tank with enough room for several to shoal comfortably. Maintaining soft, weakly acidic water is equally important.

Q.Where does its name come from?

A.The dark stripe along its body combined with the black spot at the base of the tail looks like an exclamation mark, which is how it got the English name "Exclamation Point Rasbora." This distinctive marking is the same feature behind its Japanese name.
