Here is a list of the best species that can coexist with Lake Tebera Rainbowfish:

– Diet

Just like any other creature, fishes too have stages of development. Likewise, their food needs and requirements will change with each developing stage. Let’s have a look at the section-wise food requirements of each development stage:

  • New Hatchlings

At this stage, since Lake Tebera Rainbowfish is too small, a good supply of green water (when old water is exposed to sunlight to make algal bloom) is sufficient for new hatchlings. Other options for food are infusoria and liquefy. The ideal trick here is to choose foods that will not cause choking.

  • A Week or Two Old

In this stage, baby brine shrimp or commercially prepared fry foods is the suitable option for Lake Tebera Rainbowfish.

  • Mature Lake Tebera Rainbowfish

Mature Lake Tebera Rainbowfish do not have many choices or food preferences. They can feed on anything from fish flakes to mosquito larvae, duckweed, or micro pellets.

Lake Tebera Rainbowfish: Breeding

Rearing is easier for Lake Tebera Rainbowfish as they lay eggs in abundance; however, most mature parents also eat them. Hence it is crucial to look closely for their egg-laying period and separate the eggs from the parents in good time, or else the larvae will not survive.

Both mature male and mature female Lake Tebera Rainbowfish should have separate breeding.

The composition must be of 75 percent mature tank water, and the remaining to be filled with dechlorinated freshwater. For vegetation, make sure you use fine-leaved plants or java moss as they will be used as a food source for all and as a breeding ground for the partners.

About the mating part, it happens when the mature male shows blue mating stripes on the forehead, known as an indication for mating. The female takes the hint, and they both mate, subsequently laying off eggs.

These eggs hatch after a week or so. When the eggs hatch, the hatchlings cannot feed themselves or defend themselves from another species or their parents. Hence an owner must closely keep an eye on the new hatchlings to ensure their protection.
