Signs Your Black Skirt Tetra Is Under Labor

There are a number of signs that your black skirt tetra might be under labor including heavy breathing, shaking their fins, not eating or resting properly, and being restless.

However, these signs can also indicate other issues so you should always have your aquarium checked first by an expert before acting on them to ensure the health of your fish!

Erratic Swimming

If your black skirt tetras start acting a bit more erratic than usual and hiding at the bottom of their tank instead of swimming in open water or staying near plants as much as normal, they might be going into labor!

This may also include darting around suddenly, picking up speed quickly then stopping abruptly, and being particularly aggressive towards other fish that come close.

Behavior Changes

In addition to this behavior change, there will probably be visible contractions just before giving birth which can either happen rapidly or take a few minutes depending on the size of your fish.

Swimming at the Top Of The Tank

If you look closely, this behavior might start happening just before giving birth as well!

Typically, black skirt tetra will be comfortable resting anywhere in their tank and eating from all areas. But if they suddenly begin to spend most of their time near the water’s surface it is likely that they are getting ready to give birth soon.

Aggressive Behavior

Black skirt tetra is not known for being aggressive fish but if you notice that they’re picking fights with other black skirt tetras in their tank or acting aggressively towards people while giving birth, it is likely because of the stress and excitement.

This will usually happen right after she releases all her babies so keep an eye out!

How Long Does Labor Last In Black Skirt Tetra?

The length of labor can vary among individuals because there are many factors involved including how big each individual fish is, where exactly she gives birth (near plants vs open water), and what type of environment she lives in (freshwater vs saltwater).

Keep it warm (but not too hot!). With optimal conditions, black skirt tetra should be able to give birth naturally without any problems.

However, if the labor seems to be taking too long or your fish are not getting better after a day or two you might want to consider manually extracting the fry.

Increase The Water Temperature

Increase the water temperature in their tank by about two degrees Fahrenheit as this can speed up the birthing process.

Q: Can Black Skirt Tetra Give Birth Over a Few Days?

A: Yes! It is possible for them to give birth over a few days but this can be difficult to monitor closely enough. So you should check with an expert first before acting on it as they will know immediately if there are any serious health concerns involved.
